Piezoelectric transformers (PZT) can be used advantageously in high output voltage DC-DC converters. In such applications, the output section includes a voltage doubling rectification scheme to help increase the output voltage. This topology was modeled and analyzed by considering the expected voltage and current waveforms under first harmonics approximation. The results were then used to build a linear AC equivalent circuit that emulates the AC-DC stage. The proposed model was verified against experimental results
