The utility model discloses a HID lamp high frequency drive circuit based on phase modulation, it utilizes PWM generating circuit to produce the PWM ripples to catch the wave form at its two outputs, utilize white noise generating circuit to produce stable white noise and as modulating signal, multiply each other white noise and PWM ripples through analog multiplier, signal input to the half -bridge drive circuit of realization white noise to the modulation of PWM ripples, after will making. The utility model discloses a phase modulation's mode restricts the power spectrum of HID lamp below the unstable critical value, has effectively avoided sound resonance phenomenon's appearance for luminance on every frequency point remains stable, and the frequency value can not take place the significant change, also can not appear electric arc unstable phenomenon such as twinkle, beat in the experiment.
