Design Considerations

The system functions in induction cook tops include touch and induction subsystems. The touch subsystem needs to be robust from water drops and immune from EMI. The manufacturing variation also demands time-consuming tuning to achieve optimal capacitive touch sensing performance. The induction subsystem includes a heatproof ceramic panel, which is used as the cooker plane. Through the electrified coil under the plane, the AC current creates a magnetic field that induces a vortex in iron and stainless steel pan bottom. This heats the pan bottom quickly, and then conducts the heat to food. The induction subsystem typically includes functions such as Insulated-Gate Bipolar Transistor (IGBT) self protection, temperature and power control.

This block diagram shows a Dual Induction Cooker, where the user interface (UI) and coil control are integrated to a single device. 

CapSense provides unprecedented touch performance

  • Multiple types of sensors such as buttons, sliders and proximity sensors
  • 5mm thick overlay
  • Water resistance with wipe detection across the entire panel

Visual and audible feedback with UDB based Segment LED drive and Buzzer, with minimal firmware overhead

Integrated Coil control

  • Dual coil drive
  • Pan detection implemented with programmable analog and digital blocks inside PSoC
  • Safety features implemented inside the PSoC –over-voltage, over-current and temperature protection

We developed Class B libraries along with our world-class CapSense to secure safe operation.
