Abstract
A solid state power controller off-line capacitor divider power supply coupler between an ac voltage source output terminal and neutral terminal, supplying regulated dc voltage levels referenced to the ac voltage source output terminal to a load such as the control and drive circuits of a solid state power controller. The invention circuit comprises an input capacitor having a first and second terminal. The capacitor first terminal is coupled to the ac voltage source neutral terminal. A first diode has an anode and a cathode; the anode is coupled to the capacitor second terminal. A positive filter capacitor has a first and second terminal. The first terminal being coupled to the first diode cathode and the filter capacitor second terminal being coupled to the control and drive circuit reference terminal. The invention circuit has a first positive regulator means with an input terminal, an output terminal and a reference terminal. The input terminal is coupled to the filter capacitor first terminal. The reference terminal is coupled to the control and drive circuit reference terminal. A second diode has an anode and a cathode. Its output is coupled to the control and drive circuit reference terminal and the second diode cathode is coupled to the input capacitor second terminal.
