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
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.
