Abstract

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 in response to the state of the power supply; a dissipative component; and a switch configured to The dissipative component is controllably coupled to the energy storage component in response to the control signal output by the detector. A method of operating a power supply including an energy storage component and a dissipation component is disclosed. The method includes: monitoring the power supply to determine whether the power supply may be operating; and in response to determining that the power supply may not be operating, coupling the dissipating component to the energy storage component to extract energy from the energy storage component. The storage component dissipates energy.

Description

[0001] Cross reference to temporary applications [0002] This application requirement, which is submitted on March 26, 2010, is titled "Switching energy dispersing circuit and the method for switching mode power supply ( SWITCHED ENERGY DISSIPATING CIRCUITS and Methods of Switched Mode Power Supplies ) "Temporary application serial number No. 61 / 318,005's equity and priority rights, the disclosure of the temporary application is thus referenced by the whole, as if it is proposed here. Technical field [0003] The invention involves power conversion, and more specially involves the power supply and related operation methods of switch mode. Background technique [0004] The power converter circuit can be used to transmit power from the source (such as batteries, power networks, etc.) to the load at as small as possible, such as any device, device or component running by electricity.Generally, the power converter circuit provides an output voltage, which has the level that is differ...
