US Patent 11870339 Power factor correction circuit

A power factor correction circuit configured to increase the amount of useful power in an AC electrical system. The power factor correction circuit optionally includes one or more capacitors and one or more resistors configured to realign a phase angle between a voltage and current of an AC power source. Examples are offered illustrating the disclosed circuit in use with a single phase or multi-phase AC power source ranging in voltage from 100 volts or less to 500 volts or more.
