3 level inverter - What is it? Electric motors require voltage and current to create power. To create AC motor power from a DC source, such as a battery, you need an inverter. In a 2 level inverter, the voltage and current come from the DC-Link, and are either positive, or negative (think battery "+" or "-") In a 3 level inverter, there's also a mid-point to the DC-Link. Using this mid-point, there is more control over the motor current, by using the mid-point voltage which creates a mid-level current. The higher the voltage, the higher the current. Electrical current flowing causes heating, which is lost energy. With 3 levels (or more), there is less current flowing when it isn't needed, meaning less unwanted heating and losses. This makes the inverter more efficient, meaning more miles for the available stored energy. If you want to understand in more detail, just send me a DM and we can talk more 😊
We are excited to unveil our new AMXE250 motor and HES580 inverter package for electric buses, designed to enhance efficiency and performance: https://bit.ly/3KjvYnB. Featuring the industry's first 3-level inverter, this package reduces motor harmonic losses by up to 75%, resulting in up to 12% fewer motor losses on typical drive cycles. The compact and high-torque AMXE250 motor ensures superior performance and quieter operation for a more pleasant ride. This innovation marks a significant step towards sustainable public #transportation. #eMobility #EnergyEfficiency #EnergyTransition
