Abstract :
The current sense schemes for zero-voltage switching, phase-shift bridge power converter are discussed. A new current sense scheme is proposed that can reliably and accurately sense the output inductor current and at the same time prevent the power transformer and current sense transformer from saturating in both steady state and transient conditions. The operation of the circuit is discussed. Computer simulation and experimental results are presented to confirm the analysis
