SWITCHING CONTROL CIRCUITS AND METHOD OF ACTUATING A SWITCH HAVING REDUCED CONDUCTED EMI

The present disclosure provides a control circuit to power a load, the circuit generally comprising a first switch such as a TRIAC to switch on and off and power the load based upon user demand. The circuit is also comprised of a second connected in parallel with the TRIAC, the second switch switchi...

description	The present disclosure provides a control circuit to power a load, the circuit generally comprising a first switch such as a TRIAC to switch on and off and power the load based upon user demand. The circuit is also comprised of a second connected in parallel with the TRIAC, the second switch switching to a conducting state at a zero-crossing of the source before becoming completely saturated. Once the second switch is saturated, the first switch switches from a non-conducting state to a conducting state, which minimizes conducted EMI generated in the circuit.
