Modeling and control of a three-phase push-pull dc-dc converter: Theory and simulation

This paper presents closed loop control to a three-phase push-pull dc-dc converter. The converter originally offers the advantages of compact passive devices, low conduction power losses, low output ripples around duty cycle of 1/3. The control technique is based at inner control loop by current at...

Description
Summary:	This paper presents closed loop control to a three-phase push-pull dc-dc converter. The converter originally offers the advantages of compact passive devices, low conduction power losses, low output ripples around duty cycle of 1/3. The control technique is based at inner control loop by current at switching transistors and an outer control loop by output voltage. The inner current control loop and the modulation proposed guarantee the operation of transformer out of core saturation area. Simulation results at closed loop were obtained on the mentioned converter with an input voltage of 120 V, output voltage of 48 V, load power of 500 W, and switching frequency of 35 kHz.
