Analysis of asymmetrical duty cycle-controlled DC-DC converter
with class-D ZVS inverter and full wave recti er <Abstract> This paper presents a steady-state analytical expressions of the aymmetrical duty cycle-controlled DC-DC converter with class-D zero-voltage switching inverter. The obtained expressions consider harmonic components of current and MOSFET anti-parallel diode effects. As a result, it is possible to derive accurate waveforms with low calculation cost. Experimental waveforms are agreed with the analytical ones quantitatively, which showed the validity of the analytical expressions. |
