Comparison of Parameter Calculation Methods Based on Time-domain and Frequency-domain Analysis for Class Φ2 Inverter

Due to the resonant components and complex circuit resonance in Class Φ
2
inverter, parameter calculation has always been a difficult problem. This article analyzes the inaccuracy of parameter calculation methods under frequency domain and time domain, and compares the two methods at different frequencies through simulation and experiments. Based on the simulation and experimental results, the time domain analysis method is suitable for lower frequency, and the frequency domain method is suitable when the frequency is much higher.
