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 at least one light emitting diode (LED) in a dimming application is disclosed. The driver circuit includes an input for connection to a source of dimmed AC power and a rectifier for converting the dimmed AC power from the input into DC power. The driver circuit also includes a voltage bus filter for smoothening the DC power from the rectifier. The voltage bus filter includes at least one capacitor. The driver circuit also includes a feedback circuit in electrical communication with the rectifier. The feedback circuit causes the rectifier to continuously draw current from the inputs of the driver circuit.

摘要： A driver circuit for powering a load is disclosed. The driver circuit includes an input for receiving for connection to a source of AC power, and a rectifier for converting the AC power from the input into DC power. The driver circuit also include a voltage bus filter, a high-frequency oscillator for generating a high-frequency AC signal, a resonant driver, a feedback circuit, and a high-frequency DC rectifier. The voltage bus filter smoothens the DC power from the rectifier, and includes at least one capacitor. The resonant driver is in electrical communication with the high-frequency oscillator, and limits a current of the high-frequency AC signal and produces a limited output voltage based on the high-frequency AC signal. The feedback circuit is in electrical communication with the resonant driver and the voltage bus filter, and maintains a charge on the capacitor of the voltage bus filter.
