Technology in electrification of drive systems
Electric drive systems have potential to replace combustion driven systems and hydraulic serve systems in many applications. We can extract mathematic models for different components such as motor, converter, gearbox, battery and loads. We can also model the whole drive systems for system simulations.
System modelling and simulation
Component modelling includes electric parameters and losses for components (motor, converter, gearbox, battery and loads). Co-simulation to quantify the system performance and fault handling. System modelling can also be applied to investigation and analysis of new electric system in replacing conventional drivetrains.
Machine simulator and Power HIL
To verify the control hardware and control methods, Hardware-In-the-Loop (HIL) can be used without need for hardware for the full physical systems. To verify an inverter, Power-HIL, or called machine emulator, can be utilized, in which the physical electric machine is represented with inductors/transformer and second inverter. The machine model is stored in the secondary inverter.
System design and configuration
The system to be electrified should be analysed in global and local functionalities. The possible replacements of each components should be investigated based on the various electric components. The electric components can be designed and evaluated via numerical analysis methods such as FEM, circuit simulators, and function simulators. The whole electric system should be configured and verified.
