Advantages of using a current-source for push-pull inverter in power supply applications

Abstract

• BETTER UTILIZATION OF TRANSISTORS • BETTER UTILIZATION OF TRANSFORMERS • REDUCED EMI • LESS FILTERING REQUIRED • SIMPLIFIES SHORT CIRCUIT PROTECTION Conduction overlap and core saturation are problems that must be overcome with a voltage sourced inverter operating above 10kHz. Both of these problems are controlled when a current source is used for the inverter.
