Title:
PULSE WIDTH MODULATION CONTROL DEVICE EQUALIZING SWITCHING ELEMENT HEAT DISTRIBUTION OF DUAL INVERTER, AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2022/092341
Kind Code:
A1
Abstract:
The present disclosure relates to a pulse width modulation (PWM) technique, for equalizing switching element heat distribution of a dual inverter, comprising the steps of: obtaining a positive command signal by extracting a positive signal from a command signal; obtaining a negative command signal by extracting a negative signal from the command signal; obtaining a first inverter pulse signal to be applied to a first inverter on the basis of the positive command signal and a first triangle wave in first period; obtaining a second inverter pulse signal to be applied to a second inverter on the basis of the negative command signal and a second triangle wave in the first period; and generating an output signal for the first period by applying the first inverter pulse signal to the first inverter and applying the second pulse signal to the second inverter.
