Summary

Not provided.


Description

Circuit to simulate a low pass filter used to stop lamp humming. Components V4, PWM1, and VCVS1 are meant to approximately mimic the output of a triac dimmer with bridge rectifier on output. V4 adjusts the duty ratio, which is similar to the action of changing the dimmer setting. Valid values are between 0 and 1. Run a time domain simulation to see the output.
