Abstract
An induction cooktop appliance system and method for controlling the induction cooktop appliance based on a cookware position is provided. A variable power signal can be applied to an induction coil from an inverter. The power signal can be driven at a test frequency and an operating frequency. An electrical signal can be detected across a shunt resistor based on the test frequency and a cookware position can be determined based on the electrical signal. The operating frequency supplied to the induction coil can be modified based on determined cookware position.
