摘要： A driver circuit for use with LED lamps. The driver circuit uses a rectifier, a power factor correction subcircuit, a voltage conversion subcircuit, and a semiconductor switch. The power factor correction subcircuit uses a film capacitor instead of an electrolytic capacitor. As well, the power factor correction subcircuit uses either an inductor or a transformer to shape the incoming current to a substantially sinusoidal waveform that is in phase with the input AC current. The semiconductor switch provides a high frequency pulsating triangular current at the output of the rectifier.

摘要： This invention provides an integrated power supply for a controller of an electronic ballast for a fluorescent lamp. The integrated power supply couples output power from the electronic ballast and uses the coupled power to provide power to the controller. In one embodiment, the electronic ballast may include a rectifier for converting an alternating current input voltage into a direct current output voltage, and a circuit including a combined power factor correction (PFC) stage and an inverter, wherein the PFC stage and the inverter share a switch. Also provided is a controller for an electronic ballast. The controller may include a voltage mode or current mode duty ratio controller that controls a duty ratio of a switch of the ballast. The controller and the ballast allow dimming of the fluorescent lamp while maintaining a high power factor.

摘要： An electroplated film is deposited over a substrate with a plating frame pattern that includes a plating field defined by a plurality of individual features. By dividing the plating field into a plurality of individual features, the delamination force at any location on the plating field is greatly reduced. Thus, a film with a large stress, such as a high moment film, may be plated to a greater thickness than is possible with conventionally plated films.
