| description | A power converter apparatus for converting an AC input into a DC output includes a power converter having an input circuit for receiving the AC input, one or more power switching devices to rectify the AC input and an output circuit to receive the rectified input and to provide a modulated DC output. The power converter apparatus also includes a feedback circuit for providing a feedback signal to the power converter. The feedback circuit includes a sensor for sensing the modulated DC output to generate a DC output signal and a filter to filter the DC output signal to generate a filtered DC output signal. The arrangement avoids the need for an electrolytic capacitor. The feedback signal is generated based on the filtered DC output signal. The filter may be an analogue or a digital filter. A power factor correction controller may be used to control the DC output of the converter. The power converter apparatus may be an LED driver for a plurality of LED lamps. |
