Induction heating has revolutionized the way we heat metals and other conductive materials. Whether it’s for industrial applications or DIY projects, induction heaters offer a fast, energy-efficient, and precise heating method. At Morcom Induction Pvt. Ltd., we specialize in designing and manufacturing top-quality induction heating systems. This blog will guide you through the basics of making an induction heater while shedding light on why it’s such a valuable tool.
What is an Induction Heater?
An induction heater is a device that uses electromagnetic induction to heat electrically conductive materials. Unlike traditional heating methods, induction heating doesn’t involve direct contact or an open flame, making it cleaner and safer. The process involves generating a magnetic field that induces eddy currents within the material, causing it to heat up quickly.
Why Choose Induction Heating?
Induction heating has gained popularity due to its many advantages:
Energy Efficiency: Converts a higher percentage of electricity into heat compared to conventional methods.
Precision: Targets specific areas without heating the surroundings.
Speed: Heats materials rapidly, saving time and energy.
Clean Operation: No need for combustion, making it an eco-friendly choice.

Steps to Make an Induction Heater
Making an induction heater requires basic electronic knowledge and tools. Here’s a simple guide to creating your own:
1. Gather the Required Components
To build an induction heater, you’ll need:
Copper Coil: This serves as the induction coil to generate the magnetic field.
Power Supply: A DC power supply is ideal for DIY projects.
Capacitors: Used to create a resonant circuit with the coil.
Transistors or MOSFETs: Help control the current flow.
Resistors and Diodes: For circuit protection and operation.
Heat Sink: Prevents overheating of the components.
Printed Circuit Board (PCB): For assembling the components.
2. Design the Circuit
The basic principle involves creating a resonant tank circuit. This includes the copper coil and capacitors. The circuit should be designed to operate at the desired frequency, typically between 20 kHz and 100 kHz for small-scale applications. A ZVS (Zero Voltage Switching) circuit is commonly used for efficiency.
3. Assemble the Components
Mount the Components: Solder the transistors, resistors, capacitors, and diodes onto the PCB according to the circuit diagram.
Connect the Coil: Attach the copper coil to the output terminals of the circuit.
Add a Heat Sink: Install heat sinks on the transistors to prevent overheating.
4. Test the Setup
Before powering up, double-check all connections to ensure there are no short circuits. Use a multimeter to verify the resistance and continuity of the circuit.
5. Power Up and Use
Connect the circuit to a power supply and test it by placing a small metallic object near the coil. The object should heat up within seconds.
Applications of Induction Heaters
Induction heaters have diverse applications across various industries:
Metalworking: For forging, welding, and annealing.
Automotive: Heat treatment of parts and bolt removal.
Electronics: Soldering and desoldering components.
DIY Projects: Crafting tools, making knives, or other creative applications.
Safety Tips
While induction heaters are safe when used correctly, there are a few precautions to keep in mind:
Avoid touching the coil or heated material directly.
Use insulated tools to handle hot objects.
Ensure proper ventilation to avoid overheating.
Wear protective gear such as gloves and goggles.
