Transformerless Power Supply (MSB040E)

This circuit shows how an inductive capacitance can be used to reduce the voltage of Power supply in a low voltage Power supply. The circuit also operates with higher voltages. No regulation exists but it can be added using zener or a three-terminal regulator such as the 78xx.
