Abstract
The invention discloses a current direction detection module including a conversion unit, a bridge unit and an operation unit. The conversion unit has primary and secondary sides, wherein the secondary side has first and second ends. The bridge unit has first, second, third and fourth rectifying elements and first, second, third and fourth nodes. Each rectifying element has an anode and a cathode. The anode of the first rectifying element is coupled to the fourth rectifying element. The anode of the second rectifying element is coupled to the first rectifying element. The anode of the third rectifying element is coupled to the second rectifying element. The anode of the fourth rectifying element is coupled to the third rectifying element. The first and second nodes are coupled to the first and second ends. The operation unit amplifies two bridge voltages at the third and fourth nodes and outputs an operation voltage.
