Abstract

A switch drive circuit for a fan processor is applied to a fan processor. The switch drive circuit includes multiple upper arm switch components, multiple lower arm switch components correspondingly electrically connected with the upper arm switch components, a first drive switch unit and a second drive switch unit. The upper arm switch components are driven by a first pulse width modulation signal and a second pulse width modulation signal. The first and second drive switch units serve to receive a third pulse width modulation signal and a high-frequency puke width modulation signal. The third pulse width modulation signal is switched between a voltage high-level state and a voltage low-level state to trigger and turn on the lower arm switch components.
