Dynamic device 140 turns off, and second switch pipe K2 closes, and the drain electrode of second switch pipe K2 and the voltage at source electrode two ends start on rapidly
Rise, but owing to the 4th electric capacity C4 is charged by the second diode D2 by the 3rd electric capacity C3, reduce second switch pipe
The drain electrode of K2 and the sudden change of source electrode both end voltage, i.e. reduce voltage slope, thus, not only reduce second switch pipe K2
Higher hamonic wave, rapidly the 4th electric capacity C4 can be charged again, maintain the stablizing of second source VCC2.
If the first pwm signal of control module 150 output is high level, the first driver 130 turns on, and then controls the
One switching tube K1 conducting, the first diode D1 cut-off, the second electric capacity C2 electric discharge, owing to the first switching tube K1 is metal-oxide-semiconductor,
Discharge current is the least, and the second electric capacity C2 has enough electricity to maintain the first switching tube K1 when whole PWM cycle turns on first
The voltage stabilization of power supply VCC1.When the first pwm signal of control module 150 output is low level, and the first driver 130 is closed
Disconnected, the first switching tube K1 closes, and the drain electrode of the first switching tube K1 and source electrode both end voltage start to rise rapidly, but due to
Second electric capacity C2 is charged by the first electric capacity C1 by the first diode D1, reduces drain electrode and the source of the first switching tube K1
The sudden change of pole both end voltage, i.e. reduces voltage slope, thus, not only reduces the higher hamonic wave of the first switching tube K1, again
Rapidly the second electric capacity C2 can be charged, maintain stablizing of the first power supply VCC1
