Several basic classes of three-phase high-quality rectifiers are described. Both single-switch and six-switch three-phase rectifier topologies can be derived from parent dc-dc converters. Single-switch rectifiers are compared with the basic six-switch PWM rectifiers performing similar power conversion functions, using the measures of total semiconductor stress and active semiconductor utilizati...

The main aim of this investigation is to assess the suitability of modern power semiconductor devices for pulse power applications. Pulse power system involves the storage of energy, which is released in form of high power pulse to the load by means of a switching device. Hence the basic components of pulse power system are an energy storage element, a switch, and a load circuit. The energy sto...

This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is...

By analyzing the sources of energy and power loss in PWM (Pulse Width Modulation) controlled drivers of water electrolysis cells, it is possible to reduce the power dissipation and enhance the efficiency of such hydrogen production units. A PWM controlled power driver is based on a semiconductor switching element where its power dissipation might be a remarkable fraction of the total power dema...

A Pulsed Power System is characterized by its energy storage system, the energy can be released in the form of a high power pulse to the load, by means of a switching device. The energy storage is usually either of an inductive or a capacitive nature. The limiting device in a Pulsed Power System is often the switch, which limits the pulse peak power and the repetition rate. The conventional app...
