H03K4/62 - CPC Classification

Generating pulses having essentially a finite slope or stepped portions having triangular shape having sawtooth shape using as active elements semiconductor devices in which a sawtooth current is produced through an inductor using a semiconductor device operating as a switching device

• H03K4/625 » {using pulse-modulation techniques for the generation of the sawtooth wave, e.g. class D, switched mode} 3
• H03K4/64 » combined with means for generating the driving pulses 2
• H03K4/68 » Generators in which the switching device is conducting during the fly-back part of the cycle 0
