Experiments have been conducted to study the system and to test the performance of the system. The algorithm is implemented for generating the triggering pulses for power converter operating in generator mode and controlled width variation PWM pulses to maintain DC bus voltage constant at desired level at 300 V.
Current and Voltage Testing The main DC drive motor had an input voltage of 32 V and a constant current of 1.55 Amps with no load initiated. The power consumption for the main DC motor was 49.6 Watts. Once the capacitive load was connected from a drive belt to the main DC motor via the generation motor, the revolutions per minute (rpm) slowed down.
Brushless DC (BLDC) motors are highly suitable for usage in high-speed applications like flywheel energy storage. A bidirectional power converter (BDC) interfaces the DC power source to BLDC machine which is coupled to the flywheel.
Brushless DC (BLDC) machines are an attractive proposition for drive applications because of their high efficiency, absence of electromagnetic interference (EMI) problems and mechanical reliability because of the absence of brushes . To store the energy, the flywheel is made to accelerate up to full speed (rated speed of the motor) .
Moreover, Kambhampati et al. (2022) introduce a bidirectional DC-DC converter designed for hybrid electric drive systems, particularly in dual-battery configurations. Their design enhances energy management in EVs by offering greater control over battery energy storage, thus increasing overall system efficiency.
Multi-port DC-DC converters, which are designed to handle multiple input and output paths, are a crucial element in EV energy management systems where energy from renewable sources like solar panels is combined with the primary battery system 10, 11.
