Ground leakage current power supply

A ground leakage current power supply, comprising:

• a hot node that is coupled to a hot wire of an AC power source, and an earth ground node that is coupled to an earth ground, wherein a neutral wire of said AC power source is not present;
• a rectifier, coupled to said hot node and to said earth ground node;
• an energy storage component, coupled to a return node and coupled in series to a current limiter that is coupled to receive rectified power from said rectifier, wherein said current limiter enables said energy storage component to charge to a voltage value at a rate that limits ground leakage current to a prescribed leakage value;
• and
• a low voltage power supply comprising a linear voltage regulator, coupled to said energy storage component and to a return node, said return node providing a return reference voltage, and configured to receive said voltage value, and configured generate a regulated output voltage that is referenced to said return reference voltage.
