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
