ABSTRACT:
A hybrid drive system is for a vehicle and includes an intermediate circuit and an energy accumulator. The energy accumulator is connected to the intermediate circuit by way of a diode, whereby a transistor enabling current to flow in an opposite direction is connected parallel thereto. The transistor is placed in a blocking position in order to discharge the energy accumulator and the diode enables current to pass. If the energy accumulator is not used, the diode is also blocked by increasing the voltage of the intermediate circuit with the aid of the voltage on the energy accumulator. In order to charge the energy accumulator, the transistor is conductingly switched. The diode does not allow the current to pass in this direction.
