A bidirectional DC-DC converter is a key device for interfacing an energy storage element with a motor. The voltage of a storage battery is typically 60V or lower, while the voltage of the motor is 24V. Thus, a bidirectional DC-DC converter with a wide voltage-gain range is desired for energy storage systems to connect a high-voltage battery with a low voltage motor. The interleaved switched-capacitor DC-DC converter is used to interface battery with the BLDC motor. The main components used are converter, battery, motor and an inverter. The interleaved structure is adopted in the low-voltage side of this converter to reduce the ripple of the current through the low voltage side, and the series-connected structure is adopted in the high-voltage side to achieve the high step-up/step-down voltage gain and the efficiency of the converter is improved. The converter is used to perform regenerative braking of BLDC motor. Converters HV side is connected to a battery and LV side connected to a BLDC motor. 2 modes of operation. Motoring mode and braking mode. During motoring mode motor is driven by the battery and during braking mode the battery is getting charged. The simulation is performed in MATLAB/SIMULINK. Hardware is made.
