8.2.2.9 Operation With IGBT's
The UCC27710 is well suited for driving IGBT's in various applications including motor drive and inverters. The design procedure is as the previous MOSFET example but the VDD voltage is typically 15 V to drive IGBT devices. Use the power transistor parameters and application specifications to determine the detail design and component values. See Figure 46 below for a typical IGBT application.
Figure 46. Typical IGBT Application Schematic Refer to Figure 47 below for the UCC27710 driving 27-A, 650-V IGBT's in a high voltage sync buck configuration. The input voltage is 400 V, output 100 V with a 150-W output load. Channel 1 is the inductor current, Channel 2 is high-side IGBT VGE, Channel 3 is low-side IGBT VGE, and Channel 4 is the switch node or HS voltage.
