Internal structure of intEn - electric/hybrid vehicle inverter for high torque low voltage applications.

IntEn includes all types of inputs and outputs needed for creating an electrical vehicle. The functionality is spread within several microcontroller units and an FPGA to allow maximum performance. FPGA is used to generate a precise diagram for power inverter switches to allow maximum performance of brushless motor. It also controls the electronic CVT and provides safety operation in case of overload (due to current sensors). Separate MCU is used to control the engine in case of hybrid vehicle operation with all needed sensors (temperature, rotation frequency, oil presence, voltage, current). Another MCU is used for equipment control and communication via automotive CAN interface with full transparency for data acquisition and control.
