A generating controller of this invention performs minimum power generation via reducing engine torque fluctuations caused by load of power generation. A crank rotating angle using engine speed (Ne) and an upper stopping point as standard are detected based on pitch singles input from a crank rotating angle sensor (12). Functions of the engine speed (Ne) corresponding to the route having minimal friction force in whole circulation is used for pre-storing charge periods with different lengths. A charge period determining unit (18) compares the crank rotating angle and the charge period and inputs a charge control signal into an AND gate (104) when the present crank rotating angle is judged as the predetermined charge period. A duty determined by a regulated voltage control block (102) is set in a duty ratio setting unit (103) and is input to a switch circuit (7) when the AND gate (104) is opened.
