Variable PWM Frequency
Unlike conventional MCUs/DSPs based solutions, OLEA® enables the implementation of Variable PWM frequency which reduces the number of power transistor switching events based on current load, electric motor angle and inverter / e-motor thermal time constants.
Variable PWM frequency increases the output power of the inverter by at least 35% and up to 50% when reducing the switching frequency from 20KHz to 10KHz.
Variable PWM frequency increases the output power of the inverter by at least 35%
Control Speed and Stepped Commands
Unlike conventional MCUs/DSPs based solutions, OLEA® can support very high frequency control-loop to limit torque ripples, current ripples and losses of the electric motor. It’s then recommended to control the eMotor with stepped Commands, which at High Speed frequency will deliver a higher power and a better efficiency than conventional “FullWave” commands Inverter current rating will be further improved with OLEA®: using soft-switching
Variable PWM frequency increases the output power of the inverter by at least 35% and up to 50% when reducing the switching frequency from 20KHz to 10KHz.
LOREM IPSUM
One of a kind
OLEA® T222 is a member of OLEA family, the 1st Field Programmable Control Unit (FPCU) automotive qualified solution. FPCU is a new semiconductor architecture defined as a combination of the hardware flexibility of the AMEC® real-time Control Unit with the software flexibility of a standard processor into a single chip. AMEC® integrates parallel data paths between acquisition and actuation peripherals and the Flexible Logic Unit (FLU), an automotive specific and robust embedded programmable logic with DSP resources. OLEA® T222 also benefits from SILant®, an ASIL-D functional safety integrated architecture. SILant® raises faults coverage and reliable countermeasures usually provided at chip level as high as application level and without compromising the performances. FPCU removes software bottleneck by enabling software and hardware execution of high frequency and precise PWM control algorithm while limiting heat dissipation. Using Silicon Mobility’s FPCU, user’s control command can be programmed in hardware into FLU and delivers the following performances : 40x acceleration of data processing capabilities, Up to 20x faster hard real-time control loop and Up to 180x power consumption reduction.
