Abstract :
The paper is dedicated to a two-stage direct frequency converter (TSDFC) power switches control based on coordinate PWM strategy. It presents an algorithm of the modulating functions synthesis which assures network currents and output voltages equal to their reference values under the condition of no DC smoothing filter. The simulation results of the TSDFC operating with an equivalent RLE-load and induction motor are presented. The proposed control strategy is also applicable for the matrix direct frequency converter.
