Priority based power sharing in parallel connected boost converters is one of the simplest power sharing scheme to run the boost converters in parallel operation. in this simulation it is considered that the boost converters are physically not far from each other, and the controllers of the converters can communicate with other. One of the converters will run on higher priority which means that that converter will supply as much power as it can to the bus, and another will only supply additional power required to maintain bus stability i.e: maintain the bus voltage. Following figure shows the hardware setup of the experiment. Figure: Boost converter parallel operation experimental setup this configuration of the converter is applicable in the conditions where we need to draw as much power from a source as possible and draw only additional power required to maintain bus voltage from the secondary source. An example application case would be when there is a solar and battery-based hom...

DC-DC boost converter boosts the DC input voltage to higher DC voltages  according to the duty cycle of  PWM  applied to the mosfet used to charge the inductor.While the mosfet state is on the inductor gets charged, than when the mosfet turns off the voltage stored in inductor and input voltage gets added and appears in the output. But if only these components are used output Voltage will be pulsating and have a frequency similar to that of mosfet switching. So we need to put a capacitor in output in order to oscillating output to smoother output. Still the stored voltage in capacitor will backflow through the mosfet when it is on, So we need to place a diode in between mosfet and capacitor in order to prevent backflow of stored charge in capacitor.After these circuit requirements are completed the boost converter will be boost low voltage DC input to higher DC voltages.The circuit should look like as shown below:- Boost Converter Circuit Output Voltage calcu...
