Abstract:

Background: The Cuk converter is used to control DC link voltage between the PV and VSI. The CCM is implemented in Cuk converter to control the DC bus voltage and this helps to minimize the losses in DC-DC converter.

Methods: The speed of the BLDC motor is controlled by voltage source inverter with PWM control. The PWM pulse is generated by using Hall Effect sensor.

Results: The PWM switching of BLDC motor provides reduced switching losses and increasing the efficiency.

Conclusions: The prototype model of this circuit also developed and its performance characteristics also verified. The switching losses are reduced by using Cuk converter. The VSI also reduced the switching losses by operation in 120 degree conduction mode. The speed of the BLDC motor is effectively controlled by hall signals.

Keywords: Solar power, Cuk converter, PWM pulse, VSI, Hall effect sensor, BLDC motor.
