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. These signals are used to determine if the output voltage is in a non-linear region and to adjust 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.
• The system 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 the option to apply an offset voltage.
• The turn-on state of the switches in the inverter legs is controlled by modulating the terminal voltage command using pulse width modulation.

Potential Applications

This technology can be applied in various industries where precise control of inverter output voltage is required, such as:

• Electric vehicles
• Renewable energy systems
