Setting up a power electronics lab for students and hobbyists requires the right equipment to safely work with batteries, converters, chargers, and high-current circuits. This guide provides a complete equipment list with Indian pricing, covering budget-friendly essentials through professional-grade instruments. Whether you are a BTech student, a startup prototyper, or a serious hobbyist, this list ensures you have what you need to design, build, and test power electronics circuits safely.
Setting Up a Power Electronics Lab
A power electronics lab differs from a general electronics lab in several ways: higher voltages (up to 400V+ for inverter work), higher currents (up to 50A+ for battery and motor testing), thermal management concerns, and more serious safety requirements. The equipment list reflects these needs.

Budget vs Mid-Range vs Professional
Budget lab (Rs.15,000-25,000): Sufficient for student projects, Arduino-based power circuits, and small battery packs. Digital multimeter + USB oscilloscope + basic soldering iron + watt meter + breadboard power supply.
Mid-range lab (Rs.50,000-1,00,000): For serious hobbyists and small product development. Bench power supply + 4-channel DSO + temperature-controlled soldering station + electronic load + spot welder.
Professional lab (Rs.2,00,000+): Product development and research. Programmable power supply + high-bandwidth DSO + power analyser + thermal imaging + EIS equipment.

FAQ
What is the single most important piece of equipment to buy first?
A quality digital multimeter. It is used in every single project and measurement. Invest Rs.3,000-8,000 in a Fluke 15B+ or UNI-T UT61E — they will last 10+ years and give reliable readings that budget meters cannot match.
Can I use a phone oscilloscope app instead of a real DSO?
Phone-based oscilloscopes (using the audio jack) are limited to audio frequencies (<20kHz) and low voltages. Power electronics operates at 20-500kHz switching frequencies with high voltages. A proper DSO (even a Rs.3,000 DSO138 kit) is essential for any switching converter work.
Where do Indian students buy lab equipment?
Amazon India, Robu.in, Zbotic, and AliExpress for modules and components. For instruments, check Amazon, IndiaMart (for bulk/institutional), and SP Road Bangalore / Lamington Road Mumbai for physical electronics markets.
