摘要
An apparatus for powering and TRIAC dimming of a gas discharge lamp includes an electronic ballast for powering a gas discharge lamp from a TRIAC based dimmer connected to an AC line, an EMI filter for protecting the AC line from EMI generated by the ballast and the lamp, a DC bus without a smoothing electrolytic capacitor, a resonant DC-to-AC inverter connected to the DC bus for powering the gas discharge lamp with a high frequency current, wherein an auxiliary DC-to-DC power supply input is connected to the DC bus and a first resonant tank having in series a first resonant inductor and a first resonant capacitor, wherein the gas discharge lamp is connected in parallel to the resonant capacitor.
