    • 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. And a controlling unit configured to control said second rectifying unit by a gate control signal, said controlling unit outputs said gate control signal based on an output voltage of said regulator rectifier device with respect to a first predefined voltage in battery connected condition or third predefined voltage in battery-less condition and said positive cycle and said negative cycle of each phase of said three phase alternating current voltage from said generating device, said gate control signal enables said second rectifying unit to switch between rectification mode and shunt mode by controlling the second gate terminal of said second rectifying unit, wherein said gate control signal switches said second rectifying unit into shunt mode when the output voltage of said regulator rectifier device is greater than said first predefined voltage in battery connected condition or third predefined voltage in battery-less condition and thereby continuing the shunting of said second rectifying unit as long as said positive cycle of corresponding phase of said three phase alternating current voltage exists.

    • A power converter includes a power converter section (4) (e.g., an inverter circuit) having a plurality of switching elements (S p , S n ) in which a current can flow in a reverse direction, and a control section (10) which determines on-state time of each of the switching elements (S p , S n ) according to an output voltage of the power converter section (4), thereby switching on/off states of the switching elements (S p , S n ). The control section (10) instructs the power converter section (4) to perform synchronous rectification, and corrects the on-state time according to a drop of an on-state voltage of each of the switching elements (S p , S n ).
