Abstract

A method prevents shoot-through currents and reduces body-diode conduction time in an inverter circuit by changing dead times for transistors in the inverter circuit. A sensing resistor senses temperatures of transistors in the inverter circuit. A delay generator changes delay times in response to receiving the temperatures of the transistors from the sensing resistor. A dead time generation unit changes the dead times for the transistors in response to changes in the delay times.
