SWITCHING CONTROL CIRCUITS HAVING REDUCED CONDUCTED EMI
The present disclosure provides a control circuit to control power to a load, a typically load being a heating element. The control circuit is preferably comprised of a switch, such as a TRIAC switch, to switch from a first state to a second state. An energy bank, such as a capacitor, is also provid...

| description | The present disclosure provides a control circuit to control power to a load, a typically load being a heating element. The control circuit is preferably comprised of a switch, such as a TRIAC switch, to switch from a first state to a second state. An energy bank, such as a capacitor, is also provided, the energy bank to store energy to power a thermostat when the switch is in a non-conducting state. The control circuit is also comprised of a drive circuit to actuate the switch back and forth from the first state to the second state. The improved control circuit has been shown to have reduced conducted electromagnetic interference, which is advantageous to meet ever stricter government guidelines for circuitry conducted EMI. |
