Abstract
A circuit is provided for converting power from an AC power source to DC power. The circuit including bi-directional switches capable of conducting and blocking a current flow in both directions. One or more control switches are coupled to a bi-directional switch to enable and disable the current flow through the bi-directional switch, the control switches are controlled by a signal voltage to turn a bi-directional switch ON by discharging a threshold voltage on one of the bi-directional switch gates and turning a bi-directional switch OFF when the threshold voltage is not discharged by the control switches. Additionally, the circuit includes a transformer having one or more primary windings and a secondary winding, each primary winding being coupled to one of the bi-directional switch sources. The current flow through the primary winding is disabled when the current flow through the corresponding bi-directional switch source is disabled.
