High Voltage Architecture Modelling


The HVAM project aims to identify the causes of High Voltage noise on AC and DC buses on Hybrid and Electric Vehicles (HEV) through the development

Research challenge

High DC current ripples and overvoltages pose a threat to the working life of components like IGBT's, capacitors and batteries. Hybrid Electric Vehicles (HEV) programs can be helped by the use of verified models of the High Voltage (HV) architecture.

Project outcomes

  • To develop high fidelity models of the HV architecture including the battery, inverter, electric machine and its controller, cables, connectors and the complete system.
  • Verify the HV model using a prototype drive with optimum control algorithm and using Hardware-in-the-loop (HIL)
  • Identify the causes of noise and impact in a given Hybrid Electrical Vehicle (HEV), leading to possible solutions including design and control algorithm enhancements.
  • To quantify the impact of different control strategies on system voltage and current, hence component sizing and cost in PM machines.
  • Evaluate altenative competing electric machine topologies, both Induction Machines (IM) and Switch Reluctance Machines (SRM).
