ABSTRACT:
A system for reducing leakage current hazards is provided. The system includes an electronic component, an active shunt filter and a power source. The electronic component has a first component terminal coupled to a phase line and a second component terminal coupled to a ground. The active shunt filter device is coupled in parallel to the electronic component and has a first device terminal coupled to the phase line and a second device terminal coupled to the ground. The power source is coupled to the electronic component and the active shunt filter device via the phase line and the ground. The active shunt filter device monitors leakage currents generated by the electronic component and sets an impedance value to force any leakage currents from the ground to the phase line.
