Induction cooktops are an extremely efficient method of cooking at home that is readily available to the average consumer. By utilizing magnetic fields to create heat directly in the cookware, minimal heat is wasted. Not only does it offer faster cooking times and precise control, but it is also possible to construct your own induction stove with just iron, wire, and a power source, similar to this DIY induction cooker.
This particular induction heater comes with a unique feature. Instead of employing an air coil for heating the cookware, it utilizes an iron core. The creator of this project, [mircemk], had previously built an air core induction stove, and this new version closely resembles it, with the addition of the iron core. This design allows for using less wire and incorporates a Mazzilli ZVS driver circuit powered by power MOSFETs. Two inductors restrict the current to 20A, and the performance seems comparable to the earlier stove design.
This project makes it feasible for anyone with a suitable power supply and enough wire and inductors to construct the coils to create a homemade induction stove. [mircemk] is known for his projects involving various wire coils, such as this recent one where two overlapping air-core coils were used to make an efficient metal detector.
