Abstract
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.
Claims20
A power factor correction circuit, comprising:
- a first RC circuit including a first resistor and a first capacitor electrically connected to a first node and a second node, wherein the first and second nodes are electrically connected to separate terminals of an AC power source;
- a second separate RC circuit including a second resistor and second capacitor electrically connected to the first node and the second node;
- wherein the first resister is electrically connected in parallel with the first capacitor, and wherein the second resistor is electrically connected in parallel with the second capacitor.
