Abstract
A zero current and voltage transition technique (ZCVTT) switching circuit includes a switch, and a passive block coupled to the switch and configured to damp an input signal from the switch. The switching circuit further includes a recycle positive energy (RPE) block coupled to the passive block and configured to recycle positive energy from a positive spike from the passive block, and a recycle negative energy (RNE) block coupled to the passive block and configured to recycle negative energy from a negative spike from the passive block.
