A Wide Duty Cycle Magnetic Isolation MOSFET Drive Circuit for Aerospace High-Reliability Power Supply

A magnetically isolated MOSFET driving circuit based on a driving transformer has been widely used in aerospace secondary power supplies. Based on the analysis of two typical magnetically isolated driving circuits, a new type of driving circuit is proposed. This circuit has the characteristics of zero negative voltage, high reliability, and wide duty cycle operating range. It is very suitable for a new generation of aerospace high-efficiency high-power-density power supply topology, and it has important significance for improving the efficiency of space borne secondary power supplies.
