Overview

After a quick market introduction and an overview of a typical 48 V mild hybrid electrical vehicle architecture, this design presentation considers the architecture of a dual inverter drive system for a light electric or hybrid electric vehicle in the EU L7e category. This category limits electric drive power to 15 kW and a running weight of 450 kg for passenger types or 550 kg for goods-carrying types, excluding batteries. Typical vehicles in this category are "heavy quadricycles" - an EU classification that includes four-wheel "micro cars" such as the Renault "Twizy: as well as utility vehicles such as quad bikes. For simplicity, a 48 V motor in each rear wheel is driven independently by two inverters with common control electronics.

Attendees will learn about the electrical system architecture along with standards. The presenters will introduce a key semiconductor to realize these solutions, as well as the support you can expect from Infineon and Avnet Silica's partner network.

Key Takeaways

  • Discover key factors for designing a 48 V power inverter application
  • Understand the key semiconductor components to design a 48 V power inverter
  • Learn the support you can expect from Infineon, Avnet Silica and I&M
