CCS/TMDSHVMTRPFCKIT: TMDSCND28035

Part Number: TMDSHVMTRPFCKIT
Other Parts Discussed in Thread: CONTROLSUITE

Tool/software: Code Composer Studio

  Hi,

I am doing a research using TMDSHVMTRPFCKIT and I am in need of measuring the three phase instantaneous Grid voltages and use them in calculation to control the Reactive power fed into the Motor. Furthermore I am already using both the gpios (GPIO-22 and GPIO39) for another purpose.  How can I achieve my requirement?

Also does this kit contain an inbuilt PLL (phase locked loop) ?

Thank you in advanced

    Since this is a hardware kit and a three-phase inverter for motor control, it's used to develop and evaluate the related motor control algorithm. Could you please have a detailed description of your requirement or have a look at the following link of digital power that maybe has a similar reference for you.

    You may find a software PLL reference code in the Digital Power Software as the following link.

    Thank you for your reply,

    I have attached an overview of the basic block diagram and I am trying to control the reactive power to be fed into the motor using the kit. I am in need of a way to feed the instantaneous grid voltage measurement (digitally) to the kit in order to achieve my desired algorithm. I hope this clears the ambiguity.

    Please download the controlSUITE as the following link, and you can find the schematic for this kit. You may connect the sampling signal to the remaining pin on H2 interface if GPIO can be used for voltage measurements as you mentioned, such as the GPIO for SPI and I2C on H2.

    The default folder in controlSUITE for the schematic is as below.
