Effectively avoiding the resonance of the lamp audio, the overall circuit can increase the life of the circuit and reduce the circuit cost, and increase the overall practical value. [Embodiment] As shown in the first figure, the present invention mainly consists of a filter (1), a circuit (2), and a high-frequency commutation circuit (3); in the basin: the filter (1) can be used to power the commercial AC power supply. The rectifier circuit (2) can rectify the commercial AC power source into the first pulsating direct current of twice the frequency of the mains, and rotate the first-direct current; the high-frequency commutation circuit (3) The first-pulsating DC (four) is switched into a high-frequency money supply lamp (4) for power supply, and the starting voltage of the lamp (4) to start the lighting can be directly provided by the high-frequency commutation circuit (3), or otherwise The starter provides the starting voltage required for the tube (4). In this way, as shown in the second to third figures, the overall circuit does not need to be filtered by high-capacity electrolytic capacitors, which not only improves the life of the ballast, but also reduces the cost of the ballast. The same as the first pulsed DC voltage has the power multiplier. Low-frequency AC: The sub-frequency converter circuit (3) drives the high-voltage discharge lamp (4). The driving voltage of the lamp (4) has a change in the amplitude of the low-frequency component to avoid audio resonance.
