INVERTER DRIVING APPARATUS AND CONTROL METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17985416 titled 'INVERTER DRIVING APPARATUS AND CONTROL METHOD THEREOF

Simplified Explanation

The inverter driving apparatus described in the abstract is a system that controls the output voltage of an inverter by generating space vector modulation signals based on phase voltage commands. It determines whether the output voltage is in a non-linear region and adjusts the terminal voltage command accordingly to control the turn-on state of the switches in the inverter legs.

• The inverter driving apparatus includes an inverter with multiple legs corresponding to different phases.
• The control unit generates space vector modulation signals based on phase voltage commands.
• It determines if the output voltage is in a non-linear region by checking if the modulation signals are within a predetermined range.
• A terminal voltage command is generated based on this determination, with or without applying an offset voltage.
• The turn-on state of the switches in the inverter legs is controlled through pulse width modulation of the terminal voltage command.
