The multi-port converter proposed in this work is used for the integration of many converters in a single system. The system is the solar dc-dc standalone converter with the battery storage. The proposed integrated multiport converter consists of three separate converters they are, bidirectional PWM converter, switched capacitor converter, series resonant converter. The numbers of switches are reduced and thus the loss in the power electronics circuit is also reduced. A 300 watts prototype model of the system is implemented and the hardware results obtained is discussed and the same system is simulated using matlab software and the results are matched.
A power factor correction (PFC) based Synchronous buck-boost converter fed brushless DC motor drive and an economic solution for low power applications is presented in this paper. A voltage source inverter which comprises low switching losses is fed from the dc link voltage is used to control the speed of BLDC motor. The dc link voltage is controlled by a synchronous buck boost converter which receives power from a diode bridge rectifier unit. Analysis of PFC synchronous buck-boost converter is made and its performance was assessed under continuous and discontinuous modes of operation. A BLDC motor is well known for its low maintenance, good efficiency and higher price. So reducing the cost of the BLDC motor has become essential. Pulse Width Modulation (PWM) technique has been broadly used to control power converter circuits. The results reveals that the harmonics in the output voltage and current has been reduced compare to buck boost converter.
