Microchip Technical Article On-board chargers (OBCs) are just one piece of the EV puzzle. Traditional combustion vehicles are seeing electronic upgrades across the board, including motors, sound, sensors, braking, compressors, and charging/battery management. In fact, most non-EV cars today have as many as 40 motors, some more than 100 depending on luxury class. As
Designers of high-voltage power systems have struggled to meet customers’ needs for continued innovation when using silicon MOSFETs and IGBTs. The desired reliability is often not possible without sacrificing efficiency, nor can silicon-based solutions meet today’s challenging size, weight and cost requirements. With the arrival of high-voltage silicon carbide (SiC) MOSFETs, however, designers now have
Microchip Technical Article Advances in power-delivering technologies continue to enable industries like Electric Vehicles (EVs) to improve across the board. This includes reliability, performance, cost, size and the user experience. This white paper focuses on the the three EV charging levels and the Microchip solutions that can support several aspects of residential, commercial and
Microchip Technical Article Circuit breakers are one of the most common components used in a short-circuit and overcurrent protection circuit, especially for higher-power systems. There are many considerations for designing in this kind of protection, and this article will show: Why it’s important to build in the protection Advantages of silicon carbide (SiC)-based
Microchip Technical Article E-mobility covers a very wide range of human transportation applications — not just traction motors and EVs but also e-bikes, e-scooters and other recreational equipment. Additionally, EVs have very complex electrical systems when compared with normal cars, with two or even three different electrical busses (12V/48V/high voltage). This white paper reviews Microchip's
