The spectra for the LF inverter with beats of two-step and three-step, etc. ... study of the LF inverter was conducted on a laboratory-model 5 kW inverter unit as per the circuit diagram in Fig. 1. The output frequency of the LF inverter varied from 10-100 Hz. The HF frequencies of the inverters were taken at about 1000 Hz.
