This thesis work shows the design considerations and the implementation of an engineering model of an induction heater to follow a temperature curve in sintering processes using a graphite crucible of 40mm height and 5mm thickness. This heater is based on a half-bridge topology inverter with power up to 5kW using the ZVS switching technique. It contains a capacitor bank which, together with the working coil, form the parallel topology resonant circuit to use the inverter as a current amplifier and increase its efficiency. The resonant frequency is set at 75 kHz to obtain a penetration depth of 1.84mm. The system has a feedback loop and implements up to 5 different types of self-tuning PID control to control the temperature of the graphite crucible reaching up to 1365.7°C with a power consumption of 1.3kW. The results showed that the CohenCoon tuning method is better suited to the system, achieving to follow a temperature profile from 700°C to 1200°C more accurately compared to the other methods.
