摘要：
A pulse-width modulated (PWM) controller for dc loads does not need a large power transformer to isolate the IC control logic and signal processing circuits from ac voltage levels and line transients. Instead, a full-wave diode bridge and some filter capacitors will rectify the raw incoming ac into dc power, referenced to a floating ground. A small pulse transformer gives the isolation needed between the power-handling circuit and any control-signal sources referenced to the chassis ground.
