MODELING ANALYSIS AND CONTROL OF A DC-DC BOOST CONVERTER
SIMULATION OF DC TO DC VOLTAGE CONTROLLER USING HIGH FREQUENCY TRANSFORMER

Simulation of DC to DC Converter
In many industrial applications, it is required to convert a fixed-voltage DC source into a variable voltage DC source.
Non Conventional power generation need to step up DC voltage.
A boost converter is a DC To DC converter with an output voltage greater than the source voltage.
12V DC voltage can step up into 310V DC with 6A current.

Future Scope
SIMULATION OF STEP-UP DC TO DC BOOST CONVERTER
A dc-dc converter converts directly from dc to dc and simply known as a dc converter.
A dc converter can be used to step down or step up a dc voltage source.
The DC/DC converters are widely used in regulated switch mode DC power supplies.
The input of these converters is an unregulated DC voltage, which is obtained by suitable DC sources such as batteries, solar panels, rectifiers and DC generators.
Introduction
Simulation input voltage is 6V and output voltage is 12.7V
Simulation input voltage is 100V and output voltage is 290V

Output Voltage
This converter used in many industrial applications, it is required to convert a fixed-voltage dc source into a variable voltage dc source and at Non-Conventional power generations.
In this project propose a design components, simulation and modeling of DC to DC boost converter.
In this project I proposed simulation of step up DC to DC Boost converter control with high frequency transformer ( input voltage is 12V output voltage and is 310V with 6A current ) and open loop step up DC to DC boost converter kit.
CONCLUSION
The open loop converter kit as two parts,
1. Pulse generator part 2. Boost converter part.
Output Voltage 17.4V when Input Voltage is 6V
Output Voltage 28.8V when Input Voltage is 10V

THANK YOU
In boost converter the 12VC voltage is converted into 161V DC voltage and that 161V is control with high frequency transformer. 12V DC voltage step up into 26V DC voltage and that 26V is step up into 65V DC voltage and that 65V is step up into 161V DC voltage. From that 161V converted into 310V using transformer.
