Single-Phase Direct Boost AC-AC Converter
This paper introduces and studies a boost AC-AC converter circuit that can be used to supply power to
the 220V receivers in the 110V grids or to increase and adjust voltage at the end of long lines. High
frequency AC-AC converters have better specifications than alternative voltage phase control drives
with thyristors or TRIACs. When frequency exceeds 20kHz, noise is eliminated, filters are smaller and
efficiency is higher. The current waveform is much better, the output voltage can be higher than the
input voltage and voltage control is more accurate
