This paper presents the digital design of Sliding Mode Controller (SMC) for synchronous buck converter for high switching frequency and low-voltage applications. The buck converter is designed for a switching frequency of 3 MHz. It steps down an input voltage of 3.6V to an output voltage of 0.9V with duty ratio of 25% and maximum load current of 800mA. It utilizes a hybrid digital pulse width modulator (DPWM) consisting of second order sigma-delta modulator (Σ-Δ DPWM) with counter comparator block. Both digital SMC and Σ-Δ DPWM are realized and validated on Field Programmable Gate Arrays (FPGA) using Xilinx system generator tool. Using digital SMC and Σ-Δ DPWM, an Undershoot of 0.27% and Settling Time of 4μs is achieved for load variations of 0.3A to 0.4A. The performance of SM controller is compared with conventional PID controller in terms of dynamic response for load variations. It is shown that SM control provides consistent dynamic performance over a wide range of load variations.

The work presented in this paper is an investigation into the application of Model Order Reduction technique. A 10th order unstable and multi-input multi-output (MIMO) system of a waste water treatment plant (WWTP) is considered in this paper. The paper highlights the extension of balanced realization theory for obtaining reduced order model for unstable system. The results obtained have been compared through a performance index, Integral Square Error (ISE). Finally a linear quadratic regulator (LQR) has been designed for this low order unstable system which enables stabilization of system.

In this paper, a new load flow solution of Radial Distribution Network with main feeder and laterals is determined using Tellegen theorem. The power conservation principle or Tellegen theorem is considered at network level. Since the Distribution Networks are radial in structure with high R/X ratios, the conventional methods failed to give convergence. The researchers developed many separate load flow methods, based on this conservation of power at a bus level namely Forward Sweeping method and Dist Flow method. The proposed Tellegen theorem based algorithm is applied on to a 440V, 28 bus radial distribution system with a main feeder and laterals and the results are compared with “Forward sweeping method” and “Dist flow method”. Based on the methodology, computer program is developed using MATLAB. The bus and branches are indexed with a separate new method. It is observed that the memory requirement did not increase as the size of the distribution system increases and as the method does not have higher order equations and no trigonometric parameters compared to Forward sweeping and Dist Flow methods the proposed method is has smaller execution time.

Fuel cells are being increasingly used in wide range of applications for stand-alone and grid connected systems due to their high efficiency and low emissions. A power conditioning unit, consisting of DC-DC converter and an inverter, is invariably used as an interface between the fuel cell and the load in a typical fuel cell system for ac applications because of unregulated nature of fuel cell voltage. In this research, a comparative analysis of different input ripple reduction methods, input current ripples, the output voltage ripples, and the size of passive components with high efficiency compared with the other topologies is done. The different dc/dc converter topologies is compared such as conventional Boost Converter (BC), Multi Device Boost Converter (MDBC), and Two-Phase Interleaved Boost Converter (IBC), Multi Device Interleaved Boost Converter(MDIBC) to verify its dynamic performance. The DC-DC converter topologies are designed and investigated by using MATLAB/Simulink. The simulation and experimental results have signified that interleaved converter topology is more efficient than other dc-dc converter topologies in achieving high performance and reliability for high-power dc-dc converters.

In recent years, the quality of power supplied to the consumer devices by an ac system has become an issue of great concern due to the rapidly increasing inductive loads, electronic equipments, power electronic devices and high system voltage. Power factor correction (PFC) is a technique of minimizing the undesirable effects of electric loads that create poor power factor conditions. Correction of power factor may be effected either by transmission utility which improves the stability and efficiency of the transmission network or by individuals customers. This paper aims at the correction method using an intelligent power factor corrector based on PLC (Programmable Logic Controller) as a control system especially for the correction of the industrial power factor, which is not only required for the smooth operation of the electrical equipments used in the industries but also to minimize the cost of penalty that has to be paid to power supply utilities for having low power factor. This involves measuring the power factor value from the supply line using Power Meter and development of a PLC program to determine and trigger capacitor banks of required rating in order to compensate deficient reactive power, thus bringing power factor near to unity. The results of this paper is based on the case study on application of the proposed method in a real industrial facility.

The grid is burdened with maximum load during peak hours. In order to help peak shaving in the load curve and power control there is a constant research to incorporate renewable power in the grid. Accordingly, this paper proposes integration of Photo-Voltaic array (PV) and Plug in Hybrid Electric Vehicle (PHEV) to AC grid. Studies and analysis of the effects of the same on active and reactive power of the grid are carried out. Incremental conductance algorithm is implemented in the simulation to ensure that the PV operates at Maximum power point (MPP). A DC-DC boost converter is used for boosting the limited supply available from PV and the Battery of PHEV. Duty ratio is fixed according to the required output voltage of the inverter. A 3-level Neutral Point Clamped Inverter topology i used to integrate the renewables to the grid. Independent active and reactive power control is achieved by using direct current control strategy. Such an inverter can operate from lagging power factor to leading power factor smoothly. MATLAB/Simulink is used to perform all the simulations and study the proposed system.

Monitoring the condition of induction motors is becoming highly important in various industries. There are many more condition monitoring methods including thermal monitoring, vibration monitoring,chemical monitoring and acoustic emission monitoring. But all monitoring methods require costlier sensors or specialized tools whereas current monitoring methods do not require additional sensors. This is because of electrical quantities associated with the electrical motors such as current and voltage are measured by using current and potential transformers that are installed always as a part of protection scheme. The output point of view current monitoring is non-interfering and implemented in the motor control center remotely from the motors being monitored. The present work intends the current monitoring method is applied to detect the various types of faults in induction motor such as electrically related faults. Knowledge based fuzzy logic approach helps in diagnosing the induction motor faults. Actually, fuzzy logic is just like a human intelligent processes and natural language enabling decisions to be made based on obscure information. Therefore, current work enforces fuzzy logic to induction motor fault spotting and resolving. The motor condition is identified by using linguistic variables. Fault condition is diagnosed based on the current amplitude in addition to the knowledge is expressed in membership function and fuzzy rules. The model is designed in MATLAB/SIMULINK with the data obtained under both healthy and different faulty conditions.

This paper presents miniature hardware model of 6 pulse controlled rectifier circuit for a monopolar HVDC link. The Controlled rectifier is interfaced with PIC (16F72) microcontroller for generating various firing angles. The results of output voltage are recorded using digital oscilloscope and are compared with the theoretical values at different firing angles. Performance analysis parameters such as voltage ripple, ripple percentage, harmonics with and without low pass filter for R and RL load is obtained by varying the firing angle. Results show that the ripple factor and ripple percentage has drastically reduced with the addition of the low pass filter and also smoothens the DC output voltage which were observed in digital oscilloscope. There has been a reduction of 92% ripple for R load and 60% for RL load (for firing angle α= 90°).
