Zero-cross driving circuit

The zero-crossing driving circuit is as shown in the figure. The zero-crossing driver means the circuit can control the on/off of the current at the AC voltage zero-crossing point to reduce the switching surge amd the electromagnetic interference. In the circuit, the ZNR is the sensitive component which can be used to absorb the surge to protect the power components.
