A novel high step-up interleaved DC-DC converter with ZVZCS is proposed. Based on the coupled-inductor and switching-capacitor topology, this converter is designed by combining interleave technique and active clamp together, which can realize soft switching and high output power in the same time. During steady-state modes, the leakage inductance will resonate with two switching capacitors. Under different resonant frequencies, ZVS and ZCS can be realized for certain switches and diodes, respectively. Therefore, the switching loss and reverse recovery are alleviated, which improves the efficiency of the converter. In addition, the mode boundary map for distinguishing soft-switching modes are derived and depicted. A prototype with 24 V input voltage, 400 V output voltage and 800 W output power is implemented in the laboratory to verify the performance of the proposed converter.

In this paper, a multi-cluster-based particle swarm optimization (MC-PSO) algorithm for photovoltaic (PV) maximum power point tracking (MPPT) is proposed to promote the MPPT performance in the partial shading condition. During the tracking process, each PV module is viewed as a particle and the PV modules with similar characteristics are put into the same cluster. The particles in the same cluster can refer the information to each other to realize the MPPT in the partial shading condition. In addition, multiple sampling points can be obtained at the same time to avoid the misjudgement problem during insolation changing rapidly. Thus, the tracking speed is also improved. The simulation results used by MATLAB is done and compared with the perturbation and observation (P&O) MPPT algorithm. The accuracy of MPPT of the proposed MC-PSO is improved to 96.3% in the partial shading condition. Finally, a 2.1kW prototype is implemented to verify the feasibility. The generated energy using the proposed method compared to the conventional P&O method is increased about 13.3%.

Boost converters contain a right half plane (RHP) zero. This RHP has severe limitations on the bandwidth of controllers. Further, this RHP makes it difficult to design fast disturbance rejection approaches, such as disturbance observers (DOB). This paper tackles the problem of designing a DOB based control law of the boost converter. This is done by designing a dual loop feedback controller. The designed controller is called current-minor-loop (CML) control. With CML, it is possible to make a fast response of inductor current to track reference current. Following that, the CML can be reformulated such that the current loop is considered unity. Further, the CML is simplified to make the boost converter minimum phase (MP) system. The formulated control approach is validated by simulations using PSIM software. Then, this method is verified by experiments on a boost converter loaded with resistive load.

Radio frequency (RF) pulse power generators are used for generating plasma in semiconductor product manufacture. Recently, the technology for manufacturing semiconductor products is developing rapidly. In proportion to this development, the RF generators are required to be able to generate a higher frequency High/Low (HL) pulse output with keeping an accuracy setting to a reference voltage. In addition, this generator is required to have a high responsive and the ability of the very wide range power output. The main circuit of the RF generator is a DC-DC buck converter. A 200 kHz switching prototype converter is built by using a proposed deadbeat control method. The responsive and stability of it is confirmed through a simulation and an experiment. The results proves that the experimental circuit can generate the stable 40 V/4 V high/low output with the output overshoot suppression. The rising time is less than 80 μs.

This paper introduces design and validation of space vector pulse width modulation (SVPWM) algorithm for reliability enhancement of multilevel inverters. Thermal overheating is the main cause of shortened-lifetime and open-circuit faults of power devices. It may result from ageing of semiconductor materials due to continuous operation and various operating conditions. Degradation and faults of cooling system are also of the major causes of overheating in power components. The proposed algorithm is applied when an overheating is detected in any of the semiconductor devices and helps to alleviate the overheating from the affected device and thereby preventing the overall system from malfunction. The proposed methodology relies on using the redundancy property between the switching states in multilevel inverters to continuously evaluate a cost function of the junction temperature of the overheated devices for all possible switching sequences, then it selects the optimal relieving switching sequence. Therefore, the lifetime of the overheated device can be considerably elongated. The proposed algorithm has been designed, simulated, and experimentally validated using a T-type three-level inverter system.

In recent years, environmental problems and consumer requirements encourage more and more high efficiency and miniaturized electronic devices. In addition to that, since smaller Typical Electricity Consumption (TEC) values of office automation equipment are requested, it is necessary to realize high efficiency in a wide operating range from the energy saving mode (about 0.5W) to the rating mode (about several hundreds of watts). Furthermore, the coexistence of energy saving and low cost is hard to be achieved in conventional power supply. In this paper, a new DC-DC converter with a surge energy regeneration circuit topology is studied. A small inductor is positively attached to the power transformer to realize a high efficiency and a low noise performance. The circuit operation analysis and the results of both simulations and experiments are addressed. In this paper, various circuit topologies are built to carry out the efficiency comparison and performance evaluation with TEC values.

A single-stage LED driver with high frequency pulse is presented in this thesis. The proposed circuit integrates a boost power-factor-correction converter and a half-bridge resonant inverter into a single-stage LED driver. The boost inductor is operated in discontinuous conduction mode to achieve high power factor and low current harmonic distortion. The half-bridge resonant inverter is connected with a full-bridge rectifier to increase the utilization factor of the LED. Furthermore, the effectiveness of the LED equivalent model on the resonant circuit and the light characteristics of the LED with high frequency pulse are also discussed. Finally, a single-stage high frequency pulse LED driver is implemented to drive a 40 W LED module. Experimental results show that the proposed circuit can be operated at 100~120 Vrms and the highest efficiency is 93.14 %.

Modular Multilevel Converter (MMC) is a new converter system applied in medium- and high-voltage situation, which can be extended without limit. But with extension, the control and the structure become complex, making the cost and engineering effect not ideal. In order to simplify, this paper introduce One Cycle Control (OCC) into MMC based on the principles of carrier disposition PWM. With less hardware dependence, the Virtual Loop Mapping is used to balance the capacitor voltage, which makes further efforts to simplify the structure. The simulation and experiment validate the effectiveness of the proposed method.

This paper concentrates on the load disturbance in three phase microgrid inverter (MGI) with an isolated transformer based on virtual synchronous generator (VSG) control. The transformer can provide the VSG with inductive output impedance when placed behind the LC filter. But the load disturbance may lead to steady-state error and poor dynamic performance with only capacitor voltage feedback control. The capacitor voltage differential feedback control is proposed to damp the output LC filter resonance and thus increases the system stability margin. The output current differential feedforward control is proposed to eliminate the influence of load disturbance then obtains error-free steady-state output and excellent dynamic responses. These theoretical findings have been eventually verified experimentally both on simulation and laboratory prototypes.
