Abstract: 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.

Abstract: A heater having a cover with an exhaust port and border a intake port allowing air to enter the heater. The heated air is then dissipated through an exhaust port on the cover of the heater. The border intake and cover of the heater have a perpendicular relationship whereas the exhaust port and cover have a parallel relationship.
