ABSTRACT:
An three-level boost rectifier circuit is described for universal line applications. The boost rectifier circuit includes a boost inductor connected to the input voltage. A bridge rectifier composed of four diodes is connected between the boost inductor and two output capacitors. Two boost switches, each with two series diodes are connected between the bridge diodes and the output capacitors. A threshold switch is connected between the bridge diodes and the output capacitors. The threshold switch is closed when the input voltage is below a predetermined threshold voltage and opened when the input is above the threshold voltage. Closing the threshold switch acts to reverse bias two of the four bridge diodes, reducing the number of diodes conducting at any given moment to one. This reduces the conduction losses of the circuit at low input voltage, making the circuit more efficient at low-line inputs. Further, the configuration of the boost rectifier circuit of the present invention reduces the required voltage rating for the boost switches, making the boost switches more efficient when conducting current.
