A novel Direct Torque Control (DTC) scheme for an induction motor drive system is proposed in this paper. This method is based on direct load angle control to determine needed stator voltage vector for compensation of electromagnetic torque and stator flux error by means of new modified Space Vector Modulation (SVM) inverter controller. Objectives of motor drive control, fixed switching frequency, low torque, and stator flux ripple, consequently low current distortion and simplicity in implementation are achieved using new modified SVM strategy. Matlab / Simulink simulation verifies the capacity of the proposed motor drive to evaluate potentials such as improvement in torque and stator flux ripple, low stator current harmonic contents during full load and one step speed reference.

Nowadays, Electric Vehicles (EV’s) are considered as a solution to help the environmental issues and reducing the air pollutions. But charging and recharging of the electric vehicles, using the conventional ways, have a lot of undeniable problems that have caused EVs unpopular, even though the governments provide many subsidies and taxes to resolve such programs. Hence, the Wireless Power Transfer (WPT) for charging the battery of the EVs is presented to eliminate all the difficulties of the conventional ways such as Plug-in topology. The critical point of the WPT’s design is the receiver/transmitter pads as well as the magnetic parts of the system. Therefore, in this paper the conventional magnetic structure pads are presented and compared to each other to suggest the best structure. The four constructions of the pads that are investigated in this paper nominated as the Double-D pad (DDP), Circular Pad (CP) for the transmitter-side, and Bipolar Pad (BPP), Double-D Quadrature Pad (DDQP) for the receiver-side.

Two enhanced boost inverters with continuous input current and discontinuous input current are proposed in this paper. Applying two different switched-inductor structures in conventional continuous input current switched-inductor quasi-Z-source inverter (cSL-qZSI) can extend the ac output voltage gain of inverters in small duty cycles (shoot-through). Moreover, for the proposed topologies, a new pulse width modulation (PWM) technique with high boost ability is proposed. Compared to the simple boost (SBC) PWM technique achieving higher voltage gain with higher modulation index is the advantage of the proposed PWM technique. In this paper the governing relations of proposed topologies are calculated, then to validate the advantage of the proposed topologies, the proposed inverters are simulated in PSCAD/EMTDC with proposed PWM technique.

Harmonics and decrease in power factor occur in single-phase photovoltaic microinverters because the DC bus voltage exhibits a double frequency ripple. In order to reduce this ripple, large electrolytic capacitors which have short lifetimes are often used at the DC bus. To increase the lifetime of microinverters, it is necessary to replace electrolytic capacitors with thin film capacitors which have long lives and low capacitance. The trade-off between the output current THD and the bus voltage overshoot cannot be addressed with the ordinary bus voltage controller (PI) as reduction in bus capacitance leads to increase in the amplitude of the double frequency ripple on the bus voltage. In this paper, by using the proposed control method, a microinverter is designed and simulated so that this trade-off has been solved without using additional hardware. This microinverter is connected to the grid (220 V, 50 Hz). It has a very small 20 μF bus capacitor. The bus voltage has a negligible overshoot in response to an input power step of 200 W. THD of the injected current into the grid is 0.44% at 250 W output power. The outcomes of simulation conducted with Matlab-Simulink software confirm that the proposed method is effective.

This paper presents a phase-shifted half-bridge resonant inverter 1.6 kW (4 kV, 400 mA) for driving a magnetron for the sulfur plasm tube. In the presented High voltage power supply (HVPS), with control of the switching scheduling and the phase-shifting of the on-state, the switching losses decreased. Also, using the series-resonance circuit has provided the condition of soft switching (ZVS). The power supply, depending on the required power, can control the peak and average power in minimum-loss condition. The HVPS samples the magnetic current of the transformer and then phase-shifts the switching and balances the magnetic current of the transformer as well. The maximum power of a microwave is 1600 W and its average power is 200-400 W, which is controlled according to on-state times of the inverter. Other advantages of the proposed design are the simplicity of the power circuit, reduction in the switching losses, and the leakage inductance of the power transformer. The design results have been simulated and verified through the MATLAB software.

In this paper, a new post-fault vector control of an induction motor, fed by a faulty Cascaded H-Bridge (CHB) inverter, is presented. Among fault tolerant control methods, waveform based methods are suitable for closed-loop control and provide higher output voltage. In order to control the speed of the motor, a rotor field oriented control (RFOC) is used. During the fault, the FOC is modified to decrease the fault impact on the motor as low as possible. The proposed method is validated by means of simulation results for different loads and faults. The results show an improvement in both the final operating point and the transient response of the motor.

Maximum power point tracking (MPPT) of photovoltaic (PV) arrays is an essential concern to enhance the efficiency of the whole PV system. Under partially shaded conditions (PSC) that all modules do not receive uniform illumination, the tracking turns out to be challenging, due to the output power-voltage characteristic of the PV array exhibits multiple peaks. In mobile applications, PSC becomes more troublesome since the partial shading patterns change very fast. Therefore the tracking of the MPP should be quick and precise. In this paper a two-stage MPPT Method that combines Artificial Neural Network (ANN) and Hill Climbing (HC) is presented. In the first stage an ANN estimates the vicinity of the MPP and in the second stage, HC is performed to obtain the exact MPP. The approach is very fast which makes it suitable for mobile applications and is able to extract maximum power under uniform irradiation and PSC. The validity of the proposed method is investigated by simulations in MATLAB/Simulink environment. The simulation results show that the proposed method provides a quick and accurate tracking.

This paper presents a resonant active clamp flyback converter 1.6kW (4k V, 0.4 A) for driving a Magnetron for the sulfur plasma lamp. A magnetron is a vacuum lamp which works as a self-exciting microwave oscillator. In the presented paper, a high gain boost fly-back converter is used to achieve the High Voltage Power Supply (HVPS). An active clamp topology is utilized to decrease the main switch stress. Also a phase-shifted technique is proposed to reduce the maximum flux density of the transformer core. In addition, using the series-resonance circuit has provided the condition of soft switching. The power supply, depending on the required power, can control the peak and average power in minimum-loss condition. The instantaneous power of a microwave is 1600 W and its average power is 200-400 W, which is controlled according to on-state times of the converter. Other advantages of the proposed design are the simplicity of the power circuit, reduction in the number of switching elements, the leakage inductance of the power transformer, and switching losses. The design results have been simulated and verified through the PSIM software.

This paper tackles a common ground non-isolated bidirectional DC-DC converter for applications of micro-grids. The suggested converter consists of four main switches with their body diodes, three inductors, and four capacitors. Simple structure, vast voltage gain scope, low voltage tension in the switches and joint common ground among the input and the output are the merits of the suggested converter. Furthermore, the suggested converter provides high step-up/step-down voltage gain. Regarding the simplicity in this configuration, the control concept of the suggested converter is a straightforward conception. Doing so, this paper deals with steady-state analyses in both directions, voltage stress across the power switches, and a watchful survey in comparison between other bidirectional converters. Finally, the simulation results are concluded to validate the effectiveness of the analyses in the suggested converter.

In the proposed study, a new horizontal high step-up quasi-resonant switched capacitor multilevel converter topology is developed depend on versatile switched-capacitor basic modules and units which are series connected. The amount of utilized elements such as switch capacitors, basic modules, and units assign the magnitude of voltage in the output. The recommended inverter is capable to balance the capacitors’ voltage inherently. This structure not only does minimize the number of capacitors, but also diminishes the amount of power electronic keys, and the magnitude of the voltage on keys for specified levels optimally. The comparative analysis based on the other multilevel inverter structures and traditional ones, is conducted to attest the superiority of the suggested circuit. The obtained outcomes demonstrate that the displayed topology needs a fewer amount of switches and DC sources. The quasi-resonance technique is used to stifle the current’s spikes which rise up out of the instantaneous parallel linking the series-connected capacitors and the input source. This action reduces the amount of capacitance, increases the life of the capacitors and diminishes the electromagnetic interface. The simulation area is catered to corroborate the function of the recommended high step-up multilevel converter.
