Abstract
Bidirectional PWM DC-DC converters are widely used in Electric Vehicles (EV) for the provision of smooth speed control as well as efficient recovery of electrical energy through regenerative braking of the motor. This paper proposes a control and drive circuitry for the bidirectional buck-boost converter with wide voltage gain, as suitable for EVs. The control circuit has been realized with a PIC18F67K22 Microcontroller and the driver circuits have been developed on separate PCBs using TLP250 opto-drivers. Performance of the controller and driver circuits has been tested in the laboratory by driving a bidirectional dc-dc buck-boost converter with d.c. supply of 24 V and 6 V–400 V motor terminal voltage. All experimental results were found in close agreement with the predicted behavior.
