An on-going extensive research on multi-level and matrix converters requires physically meaningful easy-to-calculate criteria to compare numerous suggested converter topologies and voltage modulation strategies. Frequency domain voltage Total Harmonic Distortion (THD) criterion approach is too complicated and non-transparent as it involves multiple Fourier integral and results in multiple serie...

Abstract: This paper presents Simulation of three phase PWM Inverter fed Induction Motor Drive using Pspice. The proposed induction motor drive model employs only seven switches and incorporates an active current shaping feature. The boost converter at the input can give the required voltage at the input of inverter. The boost converter also improves the power factor. The drive works satisfacto...

A kind of cells cascaded multilevel converter of switched reluctance motor was proposed, which can be made up of low voltage power electronic devices and can be applied to drive high voltage switched reluctance motor. Based on introducing the main circuit topology, the operating modes and the voltage superposition law of proposed converter, the control strategy for the switched reluctance drive...

A proportional-integral (PI) controller and a sliding mode controller (SMC) are used to control a fourth-order Boost-Boost (BB) converter in continuous conduction mode with two input switches and two output voltages. Based on the equivalent control method, a closed-loop system is developed. The resultant PI gains have a nonlinear relationship with each other. The appropriate PI gains are obtain...

An ultrasonic welding system typically consists of four components: power supply, PZT converter, booster and horn. Among them, PZT converter converts electrical power into mechanical power. To improve the power delivery, the input electrical impedance of converter should be reduced. In the present study, influences of piezoelectric ring thickness and thickness of matching and backing layers on ...

In this paper, a new type of ac/ac converter is proposed. The proposed converter is capable of direct ac/ac power conversion and, except for a few small snubber elements, it does not require the use of any input inductors or a dc-link capacitor. In contrast to the matrix converter, which requires bidirectional switches, the proposed converter consists of only unidirectional switches such as ins...

The aim of this paper is to investigate the power factor correction (PFC) of Boost Converter under an average current-mode control. Boost converter topology is used to accomplish this active power-factor correction in many discontinues/ continuous modes. The boost converter is used usually it is easy to implement and works well. In this paper comparative evaluation of different techniques for h...

In order to increase the voltage gain for the new Boost converter from the solar power application. In this paper boost converter specialty is achieved 10 times that of input voltage and more than 10 times of input voltages is possible from output side by...

This paper presents novel concept of a multiple converter. It works in three modesAC-AC converter voltage regulator, AC-AC converter frequency changer and AC-DC converter. All three modes work simultaneously. AC-AC converter mode of operation alters low input frequency to high output frequency across the load. AC-DC converter mode of operates with variable amplitude across load. This concept is...
