Class D synchronous rectifiers

A current-driven synchronous regulated class D rectifier is presented. An analysis of the rectifier is presented, and parameters are given. An advantage of the proposed circuit is that peak values of voltages across its elements are relatively low if compared with its output voltage. A symmetry between the rectifier and the voltage-switching half-bridge resonant class D amplifier is shown. Due to its simplicity, the rectifier can find applications in resonant DC/DC converters operating at a constant frequency. Experimental results were in good agreement with those predicted theoretically
