6 Frequently Asked Questions about “The impact of inverter power reduction”
How can power system engineers improve traction inverter efficiency?
With increasing competition between electric vehicle (EV) manufacturers to develop models with lower cost and longer drive range, power system engineers are under pressure to reduce power losses and improve traction inverter system efficiency, which can improve driving ranges and provide a competitive advantage.
Do traction inverters reduce power losses?
Demand to reduce power losses will continue with the development of inverters that have higher power levels, especially as the number of motors per car increases, and trucks migrate to pure EV. Traction inverters have traditionally used insulated-gate bipolar transistors (IGBTs).
Why do power inverters lose power if switching frequency increases?
It is demonstrated that the power losses of power inverter are linearly increased with the rise of switching frequency, which is mainly caused by the switching losses of mosfet chips increment.
How can EV traction inverters improve Ev DRIVE range?
With EV traction inverters increasing in power to over 150 kW, choosing an isolated gate driver with maximum current strength through the Miller plateau can reduce SiC MOSFET power losses and enable faster switching frequencies and therefore higher efficiency which would improve new EV model drive range.
Why are inverter-based generators important?
The inclusion of Inverter-Based Generators (IBGs) interfaced by power electronic converters compared to the large rotating masses of synchronous machines, increases the complexity of the power systems in many ways by imposing new dynamics, harmonics, severe faults, frequency excursions and voltage stability issues [1, 2].
How does power loss affect efficiency?
Efficiency relates to lower power losses, which affect thermal performance and in turn system weight, size and cost. Demand to reduce power losses will continue with the development of inverters that have higher power levels, especially as the number of motors per car increases, and trucks migrate to pure EV.
