- Design and Simulation of Loss calculation for a DC/DC converter in MATLAB/Simulink - :

- The PWM Generator (DC-DC) block is used to pulse fire the MOSFET,GTO,IGBT switch of a one quadrant converter.
- The MOSFET block implements a macro model of the real MOSFET device.
- The Diode block implements a macro model of the real diode device.
- The Powergui block allow us to select one of these methods to solve are ciruit: Continuous or discrete phasor solution.
- The scope block shows a strip chart/graph.
- The Constant block generates a real or complex constant value signal. Use this block to provide a constant signal input.
- The display block shows the instant value.
- The sum block is used for addition.
- The gain block multiplies the input by a constant value.
- The Voltage measurment block measures the instantaneous voltage between two electric nodes.
- Output Waveform (Result) - :

- Zoomed in output graph of scope.
- The first graph shows the input voltage which is 100V .
- The second graph shows the ouput voltage which is near about 90V.
- It has reduced due to the losses in the boost converter which causes the reduction in output voltage of the boost converter.

- Zoomed out output graph of scope.
- The first graph shows the input voltage which is 100V .
- The second graph shows the ouput voltage which starts from zero and stables near about 90V.
- It has reduced due to the losses in the boost converter which causes the reduction in output voltage of the boost converter.
- Conclusion - :
- We have studied and simulated the design of boost converter, and calculating the loss of different components including power switching
device and deriving efficiency of boost converter.
