Resonance converter circuit has a pair of switching stages operated by a controller to generate a chopper voltage that is applied to a rectifier

摘要

The converter circuit has switches (S1,S2)to sample a DC voltage (U1) to generate a chopper voltage (U3). The switching time is determined by a controller (5) providing a dead band time. The voltage is applied to a resonator circuit having a capacitor(Cr)and inductance (Lr) coupled to the rectifier (7). The switching operation is dependent upon a threshold value comparison.
