In this paper, the authors presents closed loop control of non-Isolated bidirectional ZVS-PWM active clamped DC-DC converter .The converter can operate with soft-switching, a continuous inductor current, fixed switching frequency and the switch stresses of a conventional PWM converter regardless of the direction of power flow. In hysteresis control strategy try to control the current of inductor on an appropriate level and then using this current they control the output voltage by hysteresis method. Controllers were first designed using the frequency response techniques based on the small signal models of the DC-DC converters, then transformed into digital controllers using the backward integration method.
