Project 1 - Loss calculation for a DC/DC converter-MATLAB

AIM:

Project Design:

Design of boost converter, and calculating the loss of different components including power switching device and deriving efficiency of boost converter. This is applicable in power supply industry, electric vehicles etc where DC-DC converter is required to boost the voltage from DC source. All the aspects of this project with loss calculation, device selection, simulation etc are industry relevant.

Solution:

Given Data:

Vin = 100 V

Vout = 200 V

L = 200uH

C = 400uF

Rload = 40 Ohms

rL = 10 mOhms

rC = 2 mOhms

Power = 1000w

Components Selection:

BLOCK DIAGRAM:

Power source:

100v 10A Power supply used in this project

Inductor:

MOSFET

Diode

Capacitor:

Load Resistor for simulation and Calculation:

1000w , 200v, 40 ohm resistor used for the simulation purpose.

Based on above componenets selection losses were calculated

Losses calculation:

Designed losses approximately = 6.5w in may vary due to the vary in temperature and ripple in the voltage and ripple in the current

So,

Losses 30% increase and decrease in calulated values.

Efficiency of the Converter is = 99.34%
