PWM OUTPUT CONTROL CIRCUIT FOR MAXIMUM OFF-SET LEVEL

摘要

The PWM output control circuit regulates the maximum offset level for set control to transfor the pulse output into DC level by Micom. The circuit comprises a Micom (5) outputting the PWM pulse output and the mute signal, a switching section (10) delivering power supply (B+), a low pass filter (15) transfering the output of switching sect. into DC level, a mute sect. (20) muting the output of the low pass filter (15) operating in the mute signal of Micom (5) and the variable resistor (VR) providing the signal processing sect. coordinating the offset of DC output of the low pass filter (15).
