Abstract
Active AC snubbers for AC/AC converters are provided. The active snubbers are actively-controlled AC snubbers that may be used in AC/AC power converters including direct AC converters. The active snubbers provide a free-wheeling path for AC/AC converters, ensuring that the converters are tolerant of errors in measurements and timings and of faults. The desired safe commutation of the switching devices when accurate measurements of voltage and current polarities become difficult or under fault contingencies when trapped energy needs to be dispatched safely is ensured. In addition, the active AC snubber may provide equal voltage sharing among the series-connected devices and clamp output voltages.
