This paper proposes an AC-DC converter with the application of active type soft switching techniques. Boost converter with active snubber is used to achieve power factor correction. Boost converter main switch uses Zero Voltage Transition switching for turn on and Zero Current Transition switching for turn off. The active snubber auxillary switch uses Zero Current Switching for both turn on and...
Recently, the demand for high voltage and high power IGBTs has been increasing. In order to achieve a device structure with high voltage blocking capability in the 1,200V range, the non-punch-through (NPT) type with non-buffer layer IGBT has become popular. Commercially available devices today in the 600 V range are mainly PT type, and in the 1,200 V range are mainly NPT type. These two device ...
