Figure 25. Dead Band between Complementary HOB and LOB Pair PWM switching at the gates of the MOSFETs at no load (inverter mode) with 12-V battery input:
Figure 26. Maximum Duty Cycle of the PWM Switching at No Load (at the Inverter’s Output) is 88 Percent PWM switching at the gates of the MOSFETs at 400 W (inverter mode) with 12-V battery input:
Figure 27. Maximum Duty Cycle of the PWM Switching at 400 W (at the Inverter’s Output) is Increased to 98 Percent to Maintain Voltage regulation at the Inverter’s Output by Sensing the Auxiliary Winding. This Results in Slight clipping of Sinusoidal Waveform at theOutput.
