A new phase-controlled parallel resonant converter

A new phase-controlled resonant inverter is obtained by paralleling the ac loads of two identical parallel resonant inverters. A phase shift between the drive signals of the two inverters controls the amplitude of the output voltage of the new inverter. A voltage-driven rectifier is used as an ac load of the inverter which results in a phase-controlled parallel resonant dc-dc converter. A frequ...

a New Resonant Converter Circuit for Reluctance

The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.

Current-source converter on-line pattern generator switching frequency minimization

On-line pulsewidth modulation (PWM) pattern generators for current–source rectifiers and inverters offer a number of control advantages over off-line optimized patterns. However, when implemented using the principles which apply to voltagesource inverter PWM pattern generators, the switching frequency is equal to: 1) the carrier frequency in standard carrier-based implementations and 2) a funct...

Current - Fed Multi - Resonant DC - DC Converter *

A novel topology, Current-Fed MultiResonant DC-DC Converter (CF-MRC) was studied theoretically and experimentally. The main features of the proposed converter are an inherent protection against a short circuit at the output, a high voltage gain and zero voltage switching over a iarge range of output voitage. These characteristics make it a viable choice for the implementation of a high voltage ...
