<p>PURPOSE:To avoid abrupt droppage of engine rotation, by detecting abrupt increase of power generation from a recharge generator when the difference between an average power generation of the recharge generator and an instanta neous power generation exceeds over a predetermined level. CONSTITUTION:In the average power generation detecting circuit 17 in an abrupt power generation detecting circuit 11, voltage VD of a capacitor 173 is proportional to the average duty factor of a switching transistor not shown. The overage duty factor represents the average power generation of a recharge generator not shown. When the voltage VD is lower than a constant voltage VA, a comparator 174 produces a 1-level output. In on instantaneous power generation detecting circuit 18, voltage VE of a capacitor 184 is proportional to the instantaneous conduction time of STr. The instantaneous conduction time represents the instantaneous power generation of the recharge generator. When the voltage VE is higher than a constant voltage VB, a comparator 185 produces a 1-level output. Then a 1-level abrupt power generation increase signal 11a is produced from on AND gate 111. By such arrangement, abrupt droppage of engine rotation can be prevented.</p> |
