Patent ID: 8797776

Claim:
A transistor-based bridge rectifier comprising: a first alternating input; a second alternating input; a start-up diode bridge connected between the first alternating input and the second alternating input, for generating a comparator power voltage on a comparator power node and having a reference ground node; a comparator, receiving the comparator power voltage from the start-up diode bridge, the comparator for comparing the first alternating input to a comparator reference to generate a timing signal; a first boost driver, controlled by the timing signal, for generating a first gate signal, the first gate signal being boosted to a voltage greater than a peak voltage of the first alternating input; a second boost driver, controlled by the timing signal, for generating a second gate signal, the second gate signal being boosted to a voltage greater than the peak voltage of the first alternating input; a first forward transistor, having a transistor gate receiving the first gate signal, for conducting current between the first alternating input and an internal power node; a first reverse transistor, having a transistor gate receiving the second gate signal, for conducting current between the first alternating input and an internal ground node; a second forward transistor, having a transistor gate receiving the second gate signal, for conducting current between the second alternating input and the internal power node; and a second reverse transistor, having a transistor gate receiving the first gate signal, for conducting current between the second alternating input and the internal ground node.
