ZCS (Zero Current Switching)
Turning a device off at the moment its current passes through zero, so there is no current to commutate and turn-off loss and diode recovery are avoided. It suits devices with stored charge such as IGBTs and thyristors.

Notes
ZCS suits current-tail devices, while ZVS suits capacitance-dominated MOSFETs, which is why LLC uses both at different nodes.
