Abstract
A control strategy for multiphase-input multiphase-output AC to AC
series-resonant (SR) power converters is presented. After reviewing some
basics in SR power converters, a hierarchy of control mechanisms is
presented, together with their respective theoretical backgrounds and
practical limitations. The respective controllers are then presented in
a simulation context. The control scheme fully exploits the capabilities
of high-frequency power converters and facilitates the extraction of
currents at a unity power factor from the supply side, even under
transient conditions. The control scheme takes into account losses and
inaccuracies in the control electronics without deteriorating the
intended waveforms. Through computer simulation, it has been shown that,
in particular, the input current wave-shapes are greatly improved
compared to the best-available operating data
