Abstract

This paper proposed a new driving method for the stable lighting of CDM lamps. To avoid the acoustic resonance in the proposed method, the inverter output voltage will be a low frequency rectangular waveform containing a sinusoidal voltage ripple with high frequency. Moreover, the realtime power control of the inverter can be achieved by the control of switching currents. To verify the validity of tile proposed method, a prototype set-up was build and the experimental results are presented in this paper.
