HYBRID VEHICLE POWER CONTROL APPARATUS AND HYBRID CONSTRUCTION EQUIPMENT USING THE POWER CONTROL APPARATUS |
摘要 |
A power control apparatus has a generator power converting circuit (3) for converting power from a generator (2) to DC power to output the DC power to a direct-current line (8), a battery (4), chopper circuits (5, 7) for converting power from a capacitor (6) to DC power to output the DC power to the direct-current line (8), a motor-driving circuit (9) for driving an electric motor (10) based on the power supplied by way of the direct-current line (8), and a power control circuit (23) for controlling the generator power converting circuit (3) and the chopper circuits (5, 7) in such a manner that the voltage of the DC line (8) is maintained at a substantially constant level irrespective of variation of demanded power from a load (11), whereby power just enough for the demanded power from the load (11) is supplied. <IMAGE> |
