Abstract
A power adaptor for converting an alternating voltage into a direct voltage to a load is disclosed. The power adaptor includes a primary side circuit including a hot line, a neutral line for receiving the alternating voltage, and a return terminal, a secondary side circuit including a positive output terminal and a negative output terminal for outputting the direct voltage, and a protection circuit including a first non-linear resistor coupled to the return terminal of the primary side circuit and the negative output terminal of the secondary side circuit forming an electrostatic discharge path for an electrostatic current generated by the load.
