Title: INVERTER CONTROL APPARATUS AND INVERTER CONTROL METHOD
Abstract:
An inverter control apparatus (100) is provided with: an inverter control unit (130), which outputs a switching pulse to switching elements (113U-113Z) for PWM control, said switching elements being provided in an inverter circuit (113); and a temperature measuring unit (120) that measures a temperature of the inverter circuit (113). On the basis of the inverter circuit (113) temperature measured by means of the temperature measuring unit (120), the inverter control unit (130) changes a frequency of the switching pulse to be outputted to the switching elements (113U-113Z).
