Abstract
A method of regulating a motor, including monitoring an absolute voltage value across an anode and a cathode of a triode via an analog switching circuit, the triode being configured to facilitate power a motor, activating a gate of the triode via the circuit in response to the absolute voltage value being greater than a predetermined threshold, and deactivating the gate of the triode via a switching circuit in response to the absolute voltage value being less than the predetermined threshold.
Claims18
A method of regulating a motor, comprising:
- monitoring an absolute voltage value across an anode and a cathode of a triode via an analog switching circuit, the triode being configured to facilitate power a motor;
- activating a gate of the triode via the circuit in response to the absolute voltage value being greater than a predetermined threshold, and
- deactivating the gate of the triode via a switching circuit in response to the absolute voltage value being less than the predetermined threshold.
An appliance comprising:
- a motor configured to receive electrical energy from a power supply;
- a triode configured to provide converted electrical energy to the motor from a power supply in response to receiving of an uninterrupted activation signal;
- and
- an inhibition switch configured to interrupt the activation signal to the triode in response to a voltage value of the power supply being less than a predetermined threshold.

An inhibition circuit comprising:
- a scaling circuit configured to map a voltage value input of a first value into a voltage value output of a second value;
- and
- a positive comparison circuit configured to compare the second value with a positive comparison voltage value and provide an electrical signal to an inhibition switch in response to the second value being less than the positive comparison voltage value,
- wherein the inhibition switch is configured to interrupt a trigger signal from a controller intended for a triac upon receipt of the electrical signal, such that that the interruption inhibits the triac from initiating operation.
