Abstract :
This paper presented a novel testing method for identifying acoustic resonance (AR) of HID lamps. It was successfully used in a control loop of a ballast of 250 W metal halide lamps. The line voltage feedforward (LVFF) method was adopted to ensure the testing precision. The experimental results show that the proposed scheme makes the examination of AR simple and reliable
