The power supply of Fig. 1 produces a positive DC voltage +V1 at relatively heavy loading, such as +5 V at 5 A, and a negative bias voltage at much lighter loading, e.g., -5 V at 0.2 A. Because of the loading mismatch, the lower-value filter capacitor C2 as compared with C1, the coupling characteristics of transformer X, and the turn-on times of diodes D1 and D2, the -V2 transformer winding will typically exhibit a voltage waveform 10 having an overshoot 11, as illustrated in Fig. 2.
