Abstract This work proposes a one-stage bidirectional rectifier with a pre-charge voltage (VPC) based perturb-and-observe (P&O) maximum power point tracking (MPPT) algorithm for triboelectric energy harvesting. The proposed VPC-based MPPT dynamically locates the true MPP while accounting for circuit non-idealities, using a simplified implementation compared to conventional P&O methods. Consequently, it achieves 93% MPPT efficiency and 8.86× energy enhancement compared to the full-bridge rectifier. With the growth of Internet-of-Things (IoT) and edge computing, wireless sensor networks (WSNs) are widely deployed at the end where battery life is critical. Energy harvesting (EH) has been a promising solution to eliminate batteries or extend the battery life. Among various EH techniques, triboelectric nanogenerators (TENGs) harvest irregular mechanical energy but produce a high-voltage (HV) AC output (VT) with a time-varying intrinsic capacitance
