Zusammenfassung:	Voltage adapter systems for use in an appliance are provided. An exemplary voltage adapter system can include a TRIAC. The exemplary voltage adapter system can include a voltage detection circuit configured to detect an input voltage of an alternating current power signal and connect the TRIAC in series with a load of the appliance when the input voltage is greater than a threshold voltage. The exemplary voltage adapter system can include a firing angle control circuit configured to provide a gate signal to a gate of the TRIAC when the alternating current power signal reaches a phase angle. An exemplary firing angle control circuit can include a resistor, a capacitor, and a DIAC. The exemplary firing angle control circuit can be configured to trigger the TRIAC when the voltage across the capacitor exceeds a breakover voltage associated with the DIAC.
