For a proper design, the circuit elements should be chosen such that the transformer
magnetizing current, in conjunction with diode D2, operates in discontinuous conduction
mode. In a good design, the magnetizing current is much smaller than the transistor current.
Three subintervals occur during each switching period: subinterval 1, in which Q1 and D1
conduct; subinterval 2,
