一种恒流源功率管驱动电路
A Constant-current Source Drive Circuit for Power Transistors
摘要
Abstract
This study proposes a constant current source drive circuit with a full-bridge structure and dual power sources, which achieves the drive on-off with positive or negative voltage. The constant drive current is obtained by the inductance current at short circuit state. Regulating the charge and discharge time can obtain different level driving current, thus improving efficiency for power switches. The discontinued current of the inductance reduces the on-state losses of power transistors. The working principle, switching logic, and inductance's design as well as the power losses are then elaborated. The Boost circuit test shows that the circuit efficiency has increased by more than 1%with the proposed drive circuit compared to traditional drive circuit.关键词
