摘要： A phase control circuit according to the present invention is configured for connection between and AC source and an AC load. The AC source supplies an AC drive signal having a plurality of sequential positive and negative half cycles. The phase control circuit comprises first and second power switches coupled between the AC source and the AC load. The first power switch conducts current of the AC drive signal after a first phase delay during the positive half cycles. The second power switch conducts current of the AC drive signal after a second phase delay during the negative half cycles. A feedback balance circuit is coupled between the AC load and the first and second power switches. The feedback balance circuit determines a DC current component in the AC load and generates a phase delay correction signal as a function of the DC current component. At least one of the first and second phase delays is adjusted independently of the other phase delay as a function of the phase delay correction signal to limit the DC current component.

摘要： A control circuit for a gas discharge lamp according to the present invention includes a transformer having a primary run winding, a primary start winding and a secondary winding. The primary run winding is coupled to a source of an AC run signal. The secondary winding is coupled to the gas discharge lamp. A current sensor is coupled in series with the gas discharge lamp to sense current flow through the lamp. A high frequency oscillator is coupled to the primary start winding for providing a high frequency start signal to the primary start winding. In a start phase, the oscillator provides the high frequency start signal to the primary start winding to initiate ionization of the gas discharge lamp. Once the gas has sufficiently ionized in the lamp, the control circuit switches from the start phase to a run phase by removing the high frequency start signal from the primary start winding and applying the AC run signal to the primary run winding. Switching between the high frequency start signal and the AC run signal on the low voltage primary side of the transformer allows the transformer to be sized much smaller to match the operating characteristics of the bulb as opposed to its start characteristics.
摘要翻译：根据本发明的用于气体放电灯的控制电路包括具有初级绕组，初级绕组和次级绕组的变压器。主运行绕组耦合到AC运行信号的源。次级绕组耦合到气体放电灯。电流传感器与气体放电灯串联耦合以感测通过灯的电流。高频振荡器耦合到初级启动绕组，用于向初级绕组提供高频启动信号。在启动阶段，振荡器向主起动绕组提供高频启动信号以启动气体放电灯的电离。一旦气体在灯中已经充分电离，控制电路通过从主起动绕组中除去高频启动信号并将AC运行信号施加到初级绕组，从起始相切换到运行阶段。在变压器低压初级侧的高频启动信号和交流运行信号之间切换允许变压器的尺寸要小得多以匹配灯泡的工作特性，而不是其启动特性。
