4. Operation Principle
- (1)
- All the components involved are ideal, meaning that the parasitic capacitance and the conduction resistance of each switch and the voltage drop across a forward-biased diode are not taken into account.
- (2)
- For simplification purposes, it is assumed that Lm1 = Lm2 = L, and iLm1 = iLm2. Hence, vLm1 = vLm2 = vL and iLm1 = iLm2 = iLm = 1/2ii.
