Abstract
A circuit for controlling a hybrid drivetrain, including an alternating current electric machine, a first battery, a second battery, a first pair of complementary transistor switches arranged to complete a first direct current circuit to charge the first battery or to complete a second direct current circuit to discharge the first battery, a second pair of complementary transistor switches arranged in parallel and arranged to complete a third direct current circuit to charge the second battery or to complete a fourth direct current circuit to discharge the second battery, an inverter arranged to convert direct current electrical energy from the first and second batteries into alternating current electrical energy, arranged to supply the alternating current electrical energy to the electric machine, and also arranged to transmit voltage modulations caused by damping vibrations within the drivetrain, and a control unit operatively arranged to control the first and second pair of switches.
