Abstract

This paper examines the occurrence of the second voltage peak caused by the pulsed resonant converter (PRC) and investigates the potential advantages of harvesting energy from this additional peak. Analytical expressions are derived which describe the behavior of the second peak and these results are compared to SPICE simulation in order to validate the theoretical models. It is shown that an optimal design point exists when harvesting from both peaks (wt = 1.76) which is different than the optimal point using only the standard primary peak method (wt = 1.53).
