Abstract :
This paper presents a new approach to constructing an efficient integrated low profile DC/AC resonant link converter. The LC resonant circuit in the resonant DC-link converter is replaced by a planar integrated LC operating at high frequency and high power level, with an integrated passive voltage clamp. An extension of the capacitive bifilar winding of the integrated LC makes it possible to construct a very low impedance DC-link resonant busbar for the converter. Experimental results on a 3 kVA, 115 kHz prototype is presented
