Design and Control of the Half-Bridge Type Switching Regulator

반브리지형 스위칭 전원의 설계 및 제어

This paper presents the design and the optimal control method of current-fed half-brige switching regulator. To achieve fast response load current variation is fed to control input, and simple optimal control model has been derived with provision of current control loop in the control circuit. Test results show that the control system model is correct and 5ms response time has been obtained at 25 KHz switching frequency.
