摘要： A method may include controlling switches of a switching full-bridge of a signal processing system to commutate polarity of a capacitor with respect to the first processing path output and a second processing path output of the signal processing system in response to a condition for commutating connectivity of the switching full-bridge and inserting a feedforward compensation that bypasses a loop filter of the second processing path in order to prevent discontinuities caused by commutating polarity of the capacitor from being compensated by the loop filter.

摘要： A lighting system includes a controller that is configured to provide thermal management for the lighting system by distributing excess energy in the lighting system through multiple power dissipation circuits. In at least one embodiment, the lighting system is a phase cut compatible, dimmable lighting system having one or more light sources selected from a group consisting of at least one light emitting diode and at least one compact fluorescent lamp. In at least one embodiment, the controller is configured to control the plurality of power dissipation circuits in accordance with a thermal management strategy to dissipate the excess energy in the phase cut compatible, dimmable lighting system. The particular thermal management strategy is a matter of design choice. The power distribution circuits include two of more of: a controlled switch path power dissipation circuit, a controlled link path power dissipation circuit, and a controlled flyback path power dissipation circuit.

摘要： A system and method includes a controller that is configured to coordinate (i) a low impedance path for a dimmer current, (ii) attaching a dimmer to a power converter system at the leading edge of a phase-cut, rectified input voltage, (iii), control of switch mode power conversion, and (iv) an inactive state to, for example, reduce the dimmer current while allowing a dimmer to function normally from cycle to cycle of an alternating current (AC) supply voltage. In at least one embodiment, the dimmer functions normally when the dimmer conducts at a correct phase angle indicated by a dimmer input setting and avoids prematurely resetting while conducting. In at least one embodiment, by coordinating functions (i), (ii), (iii), and (iv) the controller controls a power converter system that is compatible with a triac-based dimmer.

摘要： In at least one embodiment, a lighting system includes a link path power dissipation circuit to actively and selectively control power dissipation of excess energy in a switching power converter of the lighting system. The link path power dissipation circuit dissipates power through a link path of the switching power converter by controlling a link current of the switching power converter.

In at least one embodiment, the link path power dissipation circuit includes a switch to limit the link current and dissipate power in the link path.

摘要： A lighting system includes one or more methods and systems to control dissipation of excess power in the lighting system when the power into a switching power converter from a leading edge, phase-cut dimmer is greater than the power out of the switching power converter. In at least one embodiment, the lighting system includes a controller that controls dissipation of excess energy in the lighting system to prevent a premature disconnection of the phase-cut dimmer. In at least one embodiment, the controller actively controls power dissipation by generating one or more signals to actively and selectively control power dissipation in the lighting system. By actively and selectively controlling power dissipation in the lighting system, the controller intentionally dissipates power when the power into the lighting system should be greater than the power out to a lamp of the lighting system. In at least one embodiment, the controller creates one or more intermixed and/or interspersed power dissipation phases with one or more switching power converter charging and/or flyback phases.
