Single‐phase direct AC–AC step‐down converter

Abstract

The study proposes and analyses a new circuit of direct AC-AC converter that can perform a bidirectional energy flow. The authors calculated the equations governing the functioning of the circuit. The adequate functioning and high performance of the circuit (the efficiency and waveform of the absorbed input current) were tested both by simulation and experimentally.

Input‐series‐output‐parallel connected modular high frequency isolated AC–AC converters with positive compensation of inner‐current loop

“…AC-AC converters [1][2][3][4][5][6][7] are widely used in industrial applications, such as: power electronic transformers [3], traction converters [4], etc. Those with high frequency isolation can achieve high power density and flexible voltage gain adjustment.…”
