AN2383
Application note
A single plate induction cooker
with the ST7FLITE09Y0
Introduction
This application note describes an induction cooking design which can be used to evaluate
ST components or to get started quickly with your own induction cooking development
project.
Induction cooking is not a radically new invention; it has been widely used all around the
world. With recent improvements in technology and the consequent reduction of component
costs, Induction cooking equipment is now more affordable than ever.
The design provides an opportunity to understand how an induction cooker works and to
make an in-depth examination of the various blocks and parts of this type of cooking
application such as the driving topology, how the resonant tank works, how the pot gets hot
and how to remove it safely from the cooking element.
The design is entirely controlled by a simple ST7FLITE09Y0 8-bit microcontroller, which
provides the PWM driving signals, communicates information to the user interface, and
drives the fan and relay control to the plate feedback.
