Design of a New Type Anti-surge Circuit for Airborne Radar Switching Mode Power Supply
Aiming at the question of anti-surge circuit used in airborne radar switching mode power supply which has a high effi-ciency failure in the transient frequency on-off situation,a new type of anti-surge circuit is studied in this article.Two-time con-stants are designed independently through separating gate source driver circuit and main power charge-discharge circuit.The rel-evance is eliminated and the effective protection is achieved in the conditions of transient frequent power on and off.Tradition and new type anti-surge circuits are comparative analyzed in this paper,the effectiveness of this new anti-surge circuit is proven by the result of simulation and test.This circuit also has the function of input anti-reverse and widely used in airborne radar switching mode power supply.
