ABSTRACT:
A boost doubler circuit is disclosed. The circuit comprises an input, a voltage on the input to an output voltage, a transistor arrangement coupled to the input, and a drive circuit coupled to the transistor arrangement for driving. The circuit further comprises an output coupled to the drive circuit, for receiving the output voltage, wherein an AC bridge rectifier is not required. Through the use of the boost doubler circuit in accordance with the present invention, the full wave rectifier bridge circuit of conventional boost circuitry is not required. Furthermore, since the full wave rectifier bridge has been eliminated from the circuit design, the EMC problems related to the rectifier bridge circuit are not prevalent in the present invention and also the additional power dissipation in the rectifier bridge is eliminated. This results in a more energy efficient boost circuit configuration.
