Power electronics is a crucial field focused on the conversion, control, and conditioning of electric power using semiconductor devices. These projects emphasize improving efficiency, reducing losses, and innovating power management systems for various applications. Below are five engaging power electronics project ideas with overviews, components, working mechanisms, and applications.

1. Design of a High-Efficiency DC-DC Boost Converter

This project focuses on designing and building a DC-DC boost converter to step up low voltage to a higher level with minimal power losses, suitable for energy-harvesting applications.

Required Components:

How it Works: The boost converter steps up the input voltage by storing energy in the inductor during the switch’s ON state and releasing it to the output during the OFF state. The PWM controller adjusts the duty cycle to regulate the output voltage, ensuring efficient energy conversion.

Applications: Widely used in solar energy systems, electric vehicles (EVs), and battery-powered devices that require higher voltage output from low-voltage sources.

2. Design of a Bidirectional AC-DC Converter for Renewable Energy Systems

This project involves designing a bidirectional AC-DC converter, enabling efficient energy conversion between AC grids and DC storage systems in renewable energy applications.

Required Components:

Power MOSFETs Or IGBTs
Control Circuit
Current and Voltage Sensors
Microcontroller (E.G., Arduino)
Filtering Capacitors

How it Works: The converter operates in both directions—rectifying AC to DC for energy storage and inverting DC back to AC when energy is needed by the grid. Power flow is managed by a control system, which uses sensors to monitor voltage and current levels, ensuring efficient power transfer.

Applications: This system is essential in solar and wind energy systems for grid-tied inverters, energy storage, and smart grid applications where power flow must be bidirectional.

3. Active Power Factor Correction (PFC) in Power Supplies

This project focuses on designing a power supply with active power factor correction to improve efficiency and reduce harmonic distortion in AC mains-powered systems.

Required Components:

How it Works: The PFC circuit adjusts the input current waveform to be in phase with the voltage waveform, improving the power factor. The boost converter topology is commonly used in PFC circuits to shape the input current and minimize reactive power. LTspice can be used to simulate the design before physical implementation.

Applications: This project is crucial for modern power supplies in computers, industrial equipment, and household appliances, ensuring compliance with international standards for power factor and efficiency.

4. Multilevel Inverter for Grid-Tied Solar Power Systems

This project involves designing a multilevel inverter that converts DC from solar panels to AC for grid-tied systems, offering high efficiency and reduced harmonics.

Required Components:

How it Works: A multilevel inverter generates output voltages in multiple steps (levels), resulting in a sinusoidal output waveform with reduced harmonic distortion. The DC from the solar panels is converted to a clean AC signal, which can be synchronized with the grid. The system is simulated using MATLAB/Simulink or Multisim for performance verification.

Applications: Ideal for solar power systems, wind turbines, and renewable energy integration into grids, ensuring smooth power delivery with low distortion.

5. Wireless Power Transfer for Electric Vehicles (EV)

This project focuses on designing a wireless power transfer system for EV charging using resonant inductive coupling, eliminating the need for physical charging cables.

Required Components:

How it Works: The system transmits energy from the transmitter coil to the receiver coil via resonant inductive coupling. The high-frequency inverter converts DC power to an AC signal, which is then transmitted wirelessly to the EV’s onboard receiver, where it is rectified back into DC to charge the battery. This ensures safe and efficient energy transfer without physical connections.

Applications: Wireless charging for electric vehicles, mobile devices, medical implants, and industrial automation.

Power electronics projects allow students to design systems that convert and manage power more efficiently. These projects help students gain practical experience in cutting-edge technologies like renewable energy, electric vehicles, and wireless power transfer, preparing them for careers in industries focused on energy efficiency and sustainability.
