In a hybrid electric or fully electric vehicle, the inverter serves two main functions: to convert DC power from the batteries to drive multi-phase motors propelling the vehicle, and to capture regenerative energy for use in recharging the batteries. Some of the most important characteristics of an effective inverter design include low switching losses, high efficiency, high power capability and immunity to electromagnetic interference.
Microchip’s SoC FPGAs and FPGAs provide core data acquisition, processing and display functions while providing the industry’s best reliability and security in small footprint packages crucial for building differentiated, secure and reliable automotive systems. They offer support for complex algorithms required for multi-sensor input and image processing at high speeds. FPGAs offer crucial advantages over DSPs in providing parallel processing, enabling faster responses to potential hazards.
Three-Phase MOSFET Drivers
For ease of design, an integrated MOSFET driver provides an interface between the digital signal controller and the six MOSFET array controlling the three-phase motor. These devices feature low propagation delays, anti-shoot through outputs which are guaranteed to not overlap, and an overcurrent protection and an internal diode that charges the high-side gate drive bootstrap capacitor.
