Abstract:
1. A multiphase control system, adapted to convert power of an input power source into an output voltage for outputting through an output terminal, the multiphase control system comprising: a plurality of control units, connected in series to form a loop, wherein each of the control units determines that whether the output voltage is lower than a first voltage value, each of the control unit generates a control signal to transmit power from the input power source to the output terminal and a sequential output signal at a multiphase output terminal for outputting to an adjacent control unit connected there after when determining that the output voltage is lower than the first voltage value after receiving a sequential input signal from an adjacent control unit connected there before through a multiphase input terminal, each of the control units comprises a bypass circuit making the multiphase output terminal output the sequential output signal when the control unit receives the sequential input signal and the bypass circuit is activated, wherein when each of the control units generates the sequential output signal and determines that the output voltage is lower than a third voltage value, the control unit generates a succeeding bypass output signal to activate the bypass circuit of the adjacent control unit connected there after, where the third voltage value is lower than the first voltage value, or when each of the control units detects that the output voltage is lower than a fourth voltage, the control unit generates a preceding bypass output signal to activate the bypass circuit of the adjacent control unit connected there before, where the fourth voltage value is lower than the first voltage value.
