A MOSFET Pushpull Circuit which Prevents the Output Circuit from Oscillation Causing Reverse Recovery Current of MOSFET and Parastic Components

역회복전류와 기생소자들에 의한 발진 방지용 MOSFET 푸쉬풀 회로

The general output circuit for PWM output is pushpull using a complimentary MOSFET. The gate driver coupled directly at gate can switch easy upto a high frequency. However, a high reverse recovery current and parastic components make a oscillation output. This paper analyses this phenomenon and proposes a novel output circuit preventing the oscillation.
