The series-resonant converter comprises an input bridge, a series capacitor with capacity C, a transformer showing high mutual inductance and a rectifier. Thus, the transformer can be represented by its leakage inductance L and an ideal transformer with turns ratio r = N1/N2, as depicted in Fig. 1. Input and/or diode output bridge might differ from the depicted version comprising an input full-bridge and an output voltage doubler. This version is preferred in case high output voltages should be generated out of low input voltages.
