Stored Energy Dissipating Circuits and Methods for Switched Mode Power Supplies
First Claim
1. A circuit, comprising:
- a detector configured to detect a state of a power supply including an energy storage component and to generate a control signal responsive to the state of the power supply;
a dissipating component; and
a switch configured to controllably couple the dissipating component to the energy storage component in response to the control signal output by the detector.

Abstract
A circuit includes a detector configured to detect a state of a power supply including an energy storage component and to generate a control signal responsive to the state of the power supply, a dissipating component, and a switch configured to controllably couple the dissipating component to the energy storage component in response to the control signal output by the detector. Methods of operating a power supply including an energy storage component and a dissipating component are disclosed. The methods include monitoring the power supply to determine if the power supply may be active, and, in response to determining that the power supply may be inactive, coupling the dissipating component to the energy storage component to dissipate energy from the energy storage component.
