# Power Electronics Projects

Power Electronics Projects is the important application of solid state electronics to control and conserve electric power. We offer power electronics projects in matlab for students encompass use of electronic components. We implement power electronics projects from science direct paper switching power supplies, motor drives, power converter and motor soft starters. We ensure matlab as numeric computation software for engineering and scientific calculations. We use matlab for B.Tech students to ensure circuit theory, random process, control system and communication theory.

## Power electronics in DC-DC converters:

Power electronic converter requires modeling and simulate converter by modeled equation. It performed by state equation and matlab simulink tool for simulate state equation. It contain power electronic converter, using system level non linear and switched state space model.

## Matlab/ simulink for power electronics:

We perform modeling & simulation of power electronic converter by matlab simulink as:

## Sine wave:

It used to generate sinusoidal input with amplitude, frequency & phase.

## OR logic:

It is used to turn off thyristors when current reaches zero.

## Repeating sequence:

It is used to generate number of pulses in terms of time.

## Switch function:

It is used to switch among sine wave from & firing pulse generated from repeating sequence.

## Open loop model for DC-DC converter:

It composed of:

• Buck boost converter model.
• Subsystems.
• Buck converter model.
• Boost converter model.
• Cuk converter model.

## Closed loop model for DC-DC converter:

• Boost converter.
• Cuk converter.
• Buck converter.

## Dynamic voltage restorer in power electronics:

We implement DVR a series connected solid state device for mitigate voltage disturbance in system by injecting voltage to regulate load side voltage. We maintain load voltage at nominal magnitude and phase by compensating voltage, voltage unbalance & voltage harmonics at point of common coupling.

## Components of DVR:

We provided the DVR components:

• Voltage source inverter
• DC charging circuit
• Passive filters

## Control and protection:

It composed of hardware with programmable logic.

## Types of filter Algorithm:

We categories filter algorithm for academic projects and listed as:

• Phase locked loop (PLL).
• Fourier transforms (FT).
• Wavelet transforms (WT).

## Categories of DVR in power electronics:

We developed more than 80+ projects in power electronics and DVR are categorized as:

• In phase compensation.
• Phase advanced & minimum energy compensation.
• Pre-sag compensation.
