How to size the resonant tank of the Induction Cooking Evaluation Board
The document provides technical guidance on sizing the resonant tank circuit specifically for an induction cooking evaluation board. It details the characteristics of a series resonant circuit consisting of a capacitor, inductor, and resistance, noting that the cooking element itself acts as the inductor (L). The text explains how to calculate resonance frequency and describes the behavior of the system relative to the resonant curve.
The operating frequency is in a range between 19 and 60 kHz.
The MCU provides the driver with a 50% constant duty-cycle.
The system power factor is around 0,98.
