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.
