Analysis of class D inverter with irregular driving patterns

This work presents an analysis of class D inverter when irregular driving patterns are given to the gate drive of the switch devices. The analysis has been carried out with focusing on the waveforms, harmonics, low frequency components, and equivalent dc resistance, which are numerically analyzed and discussed. Appropriate patterns are sorted based on the calculation results. The waveforms are compared to the circuit experiments. These results corresponded with the calculation. Analytical results show a possibility of control method with irregular driving patterns. In spite of discontinuous control, the output pattern or voltages can be strictly changed using the selected driving patterns.
