This paper provides a zero-current-switching (ZCS)-pulse width modulation (PWM) half-bridge boost rectifier with output voltage balance control using ZCS auxiliary resonant circuits. In the proposed ZCS-PWM half-bridge boost rectifier, ZCS in the active switches and ZCS in passive switches are performed without additional current stress. In addition to reduce switching losses, significant reductions...
In inverters, distortions of output sine voltages caused by factors like dead-times of power switches can be well compensated by instantaneous voltages and/or currents feedback regulators such as PID or repetitive controllers. However, in our experiments, we found that the dead-time differences between inverters would result in significant harmonic circulating currents, and instantaneous regulators...
