Document Type and Number:
Japanese Patent JPH0284026
Kind Code:
A
Abstract:
PURPOSE: To collect the maximum amount of energy, by forming an impedance of the primary winding of a transformer, and connecting the secondary winding thereof to a secondary AC circuit including a collecting element. CONSTITUTION: The secondary winding of a transformer T is connected to a secondary AC circuit 8, the AC diagonal line of a secondary rectification bridge P2 is inserted into the circuit, and the DC diagonal thereof is inserted into a secondary DC circuit 9 connected by itself in parallel to the primary DC circuit 3 including a primary rectification bridge P1 and a battery 4. At a low speed, Ua .2<1/2> becomes higher than the voltage Ub of the battery 4 and at the same time the direct current Ic of the battery 4 and the part of a DC circuit in common with the primary DC circuit 3 and the secondary DC circuit 9 is actually equal to a alternating current Ia . When a speed is increased, a reactive voltage is generated at the terminal of the primary winding 5 of the transformer T for inducing a voltage to the secondary winding 6 of the transformer T, and an additional current appears at the branch of the bridge P2 and the secondary DC circuit. The current is added to the previous current of a common part Ic . As a result, an additional charging current proportional to the rotating speed is generated.
