摘要： A driver circuit for powering a load is disclosed. The driver circuit includes an input for connection to a ballast, a rectifier, a switch, and a fault circuit. The rectifier converts AC power received from the input into DC power. The rectifier includes a rectifier input. The switch is electrically connected to the rectifier input. The switch is activated to create a short circuit at the rectifier inputs in response to receiving an activation signal. The fault circuit is electrically connected to the switch. The fault circuit generates the activation signal in response to detecting at least one of an over voltage, an over temperature, and an over current condition of the driver circuit.

摘要： A driver circuit for powering a load is disclosed. The driver circuit includes a self-oscillating half-bridge circuit, a resonant driver in electrical communication with the self-oscillating half-bridge circuit, and a DC voltage supply in electrical communication with the resonant driver. The self-oscillating half-bridge circuit is configured to generate a high-frequency AC signal. The resonant driver is configured to limit a current of the high-frequency AC signal and produce a limited output voltage based on the high-frequency AC signal. The DC voltage supply is configured to rectify the limited output voltage into a DC output voltage including a substantially constant current for powering the load.

摘要： The present application claims a compact low cost topology solution of a ballast for a discharge lamp that can provide both high power factor and low total harmonic distortion with fewer components than prior art. The topology provides the feature of a low crest factor and quick start that increase both the lamp life and the number of starts for the product. By using Bipolar Junction Transistor instead of Field Effect Transistor as the main switches and also a lower value electrolytic, the cost and size are considerably reduced.

摘要： A single-converter circuit-based LED driver circuit (10) with isolated multi-channel outputs is disclosed. The circuit (10) includes an IC control circuit (11), a plurality of isolated output channels (70, 74) each having an output current sensing and conditioning circuit (74, 90), and an output current regulation circuit (128). The output current regulation circuit (128) includes a voltage-sensing transformer winding (T4) that senses an output voltage level across a secondary side of the circuit (10), and a peak output current sensing component (156) that senses output currents from the isolated output channels and determines which channel has a highest current output. Additionally, the circuit (10) facilitates providing output current regulation when detected output voltage is below a predetermined threshold, and providing output current regulation when the detected output voltage is above the predetermined threshold.

摘要： A higher power package is provided in a smaller package by providing at least first and second magnetics in parallel in first and second transformers. To limit degrading performance associated with circulating current between the two transformers, the transformers are electrically decoupled. In a preferred embodiment, the circuit includes parallel primary and secondary windings of the transformer that are decoupled electrically on an output side. Particularly, diodes are provided in a preheat portion of the circuit so that once the preheat phase is terminated, the diodes prevent current flow in one direction through the preheat portion of the circuit.
