Abstract
Techniques and circuits for controlling a multi-phase electric motor and measuring current through the multi-phase electric motor without using a shunt resistor are described herein. A method may comprise controlling power switches of an inverter circuit to deliver a first phase current, a second phase current, and a third phase current to a multi-phase electric motor, and determining at least one of the first phase current, the second phase current, and the third phase current based on a first voltage drop over one of the power switches in a conducting mode and based on a temperature measurement, wherein the temperature measurement is based on a second voltage drop over a body diode of one of the power switches in a nonconducting mode during a dead time.
