The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

This paper analyses a PWM control circuit for a three-level three-phase inverter. The power circuit of inverter and the PWM control principles, using a mirror triangular waveform, are explained. The ...

Aiming at the problem of poor human auditory sensation caused by the wide range variation of audio signal amplitude, a high-precision and expandable automatic volume control circuit system is designed ...
