Abstract: A regulator rectifier device and a method for regulating an output voltage of the same which takes input from three phase alternating current voltage generating device with each phase including a positive cycle and a negative cycle. A first rectifying unit with a first gate terminal, connected to the generating device to rectify the positive cycle of said three phase alternating current voltage. A second rectifying unit with a second gate terminal, connected to said generating device to rectify the negative cycle of said three phase alternating current voltage, wherein said second rectifying unit switches between rectification mode and shunt mode depending on the load condition.
