Abstract
Systems for power factor correction are provided. Aspects include a voltage source connected to a first node, wherein the voltage source is configured to provide a first voltage, a sense resistor connected between the first node and a second node, a load connected to the second node, a power factor correction capacitor connected in parallel with the load, and a controlled voltage source configured to provide a second voltage to the power factor correction capacitor based on a control signal, wherein the control signal is received from a power factor correction circuit configured to determine a time difference between a zero-crossing of a voltage signal and a zero-crossing of a current signal from the voltage source.
