Abstract
In this work, an H bridge was built and controlled to be used as a frequency variator in electromagnetic induction heating. Due different frequency values are required for this process depending on its diameter, it is necessary to adjust the pulse rate for each specific case. The H bridge was built using the N type MOSFET, model IRF640. Its driving capacity is 18 Ampere and it can operate at 200V. For its operation, the integrated circuit IR2110 was used, which can operate a MOSFETS or IGBTs bridge that works up to 500V. Pulse generation was performed with the Arduino board. As a result, a load frequency of 5 KHz was achieved, which is sufficient for use in induction heating of an inch diameter steel bar.
