Impact of UnitedSiC Gen 4 Technology on Electric Vehicles

Table 1: Comparison of parameters for G4 750V SiC FETs with similar 650V SiC MOSFETs and 600V Superjunction fast diode FETs

The automotive market for Silicon Carbide (SiC) devices is widely expected to exceed the $1.5 billion threshold in 2025 with an annual growth rate (CAGR) of 38 percent. This is driven by the value provided by SiC based components in On-board chargers, DC-DC converters and in Traction inverters. With the launch of

Figure 1. A simple Zener regulator circuit

The subject of power supplies is potentially very broad and the application of resistors in power supplies is quite diverse. Here we will focus on power supply units (PSUs) designed for use in electronic appliances that nominally require fixed DC outputs ranging from just a few volts up to a few kV. Whether
