N2 - A numerical analysis of a Class D zero-voltage switching (ZVS) inverter in the time domain is presented along with experimental results. A discrete-time state-space approach is used for simulation. The state-space description and simulation results provide a fast insight into the physical operation of the converter. The algorithm is fast, easy to implement, and suitable for systems with high spikes in the waveforms and variable inputs. The analysis shows that switching losses can be reduced by using a dead time in the transistor drive voltages and adding a single capacitor in parallel with one of the transistors. ZVS can be achieved above the resonant frequency and in a limited range of the load resistance. The numerical results are in good agreement with the experimental ones. Index Terms- Resonant converters, series resonant inverter, simulation, zero-voltage switching.
