With the advent of Electric Vehicles and Internet of things the need for sophisticated power electronic design has increased. These new fields are constantly evolving the demands for high-power motor drives, energy efficient power supplies, wireless power transfer etc.
In this section we will design and test various power electronic projects for a wide variety of applications including EV, Solar, IoT, SMPS Power supplies, LED Drivers, Portable power supplies etc. The section also covers the latest power electronic news and articles to update the readers with latest technology trends.
Bulky bench power supplies and dedicated adapters are still common on electronics workbenches, but they are often inconvenient to carry around and overkill for many portable or field setups. With USB Power Delivery and newer GaN chargers now able to provide high power from compact adapters, developers are starting to treat USB-C as a serious power source rather than just a charging port.

In this project, we upgraded LiteWing, an ESP32-based development drone by adding a lightweight Bluetooth speaker system to extend its capabilities beyond flight. By adding a simple Bluetooth audio setup, the drone can now deliver real-time announcements, voice messages, or music directly from the air without requiring any additional coding. The entire system works…
You’ve just finished assembling an electronic project and are ready to power it up, only to realize the battery might be connected backwards. In an instant, a simple mistake can destroy hours of work. Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity…
ROHM has developed the “BD9xxN5 Series” of LDO regulator ICs with 500mA output current, featuring its proprietary ultra-stable control technology “Nano Cap™”. This series comprises 18 products designed for 12V/24V primary power supply applications used in automotive equipment, industrial equipment, and communication infrastructure.
In recent years, electronic devices have demanded…
Text-to-Speech, or TTS, is a technology that converts written text into spoken audio. It is widely used in voice assistants, accessibility tools, alert systems, kiosks, and smart devices. Today, ESP32 Text to Speech using AI has become a common approach for adding voice output to small electronic projects. On computers and smartphones, TTS works smoothly because…

We have developed a smart home energy management system prototype that divides the house into sectors and efficiently chooses which sector is powered by what energy source. The reason why we developed this project was that in India, the adoption of renewable energy is still not widespread, despite the subsidies and…
A new breadboard-friendly power supply called ProtoV MINI has been announced and is expected to launch soon. Roughly the size of a credit card, the device is designed to plug directly into a standard breadboard and power both rails independently using a single USB Type-C input. Each channel can be adjusted up to 20 V with fine digital control and includes current limiting and built-in…
ESP32 text to speech becomes a really helpful feature that can turn an embedded project from good to really useful. Whether you're building a handheld device, automation panel, safety monitor, or educational tool, implementing text to speech in ESP32 makes your project more accessible and user-friendly. Over time, we’ve tried many different ways to do this. Our…
Power Integrations displayed a wide array of new tech for applications including EVs, railways, industrial power supplies, and renewable energy systems at electronica 2025. In their booth, we met with Andrew Smith, their Director of Technical Outreach and Director of Training, who walked us through some of the key highlights. The company showcased its range of switch…
Infineon and ROHM have signed an MoU(Memorandum of Understanding) that lets them act as second sources for each other's customers using certain SiC products with applications including electric vehicle on-board chargers, solar photovoltaic systems, energy storage, and AI data centres. This will make both the design and procurement process easier for the customer. The standardisation of…
DigiKey has announced its Back to School Giveaway, and it’s open for submissions from August 26th to October 24th, 2025. The winners' announcement is expected around the 15th of November. This is a giveaway that happens every year, and the company sees this as a way to help students bring their creative engineering ideas to life.
The entry eligibility is for you to be a student with a…
Traditional analog power supplies struggle to keep up with today’s performance and control accuracy requirements, which have gotten way stricter. Even though digital power supplies work better, they’re just too expensive and use too much power for smaller industrial applications. This makes their use limited. To counter this, ROHM has just announced a new reference design for power supply…
