Miniaturized High Frequency AC Generator Construction

Simulation on High Frequency AC Generator

A DC-AC converter with a full-bridge inverter and LCLLC resonant tank are modeled and simulated using PSpice software based on the above theoretical analysis and parameters selection, which is shown in Fig. 3a. The detailed parameters of the resonant converter are listed in Table 1. This study aims to generate a 200 kHz AC waveform (above 50 V) using a regular lithium battery, utilizing a 3.7 V DC supply for the simulation. As shown in Fig. 3b, the output AC waveform generated by the LCLC structure is 33.6 V, while the LCLLC structure produces 53.8 V. The voltage gain for the LCLC structure is only 9.08, whereas the LCLLC structure achieves a gain of 14.54 (Fig. 3b).Table 1 Design Parameter of the Proposed Resonant Converter
