DC rails side diode clamped-active edge resonant PWM DC-DC converters with HF link

This paper presents a new circuit topology of active edge resonant snubbers-assisted soft switching symmetrical PWM inverter type DC-DC high power converter with a high frequency planar transformer. Its operating principle is described by using switching mode equivalent circuits, together with its unique features. The performance evaluations of its experimental setup are actually illustrated on the basis of the power loss analysis. The practical effectiveness of new DC-DC converter treated here is proved for low voltage and large current DC output implementation. The extended circuit topologies of DC-DC converter treated here are also demonstrated and discussed in this paper.
