1.Parallel Capacitor The simplestturn-off snubber circuitis to add the switch with a parallel capasitor Cv, which is shown in picture 1 (a), to limit the rising speed of the switch tubevoltage during its closing time which is shown below. The current before the switch tubeclosed is Io. The more Cv is, the slower therising speed of the switch tube voltageis, and the less power consumption of switch would be. The picture 1(b) and (c) shows the Uv, Iv and P during the closing time in separately. The picture 1 shows the parallel capacitor of the switch tube in the buck converter.
