Abstract

Applications of new high-voltage bipolar-power MOSFET cascode monolithic devices are developed. The device features of this smart-power emitter-switching component are described both in terms of physical structure and electrical performance. Firstly, the device is characterized in a soft-switching zero-voltage (ZV) test circuit. Experimental tests are carried out under several working conditions in order to understand the main advantages and drawbacks of the switch. Finally, actual ZV applications, such as a step-down ZV quasi-resonant converter (QRC) and a TV deflection circuit, are presented and discussed
