A system and a method for industrial communication, employing an adaptive repeater supporting communication between at least two communicating devices using one of two or more predetermined communication protocols at a time instant, are provided. The adaptive repeater includes a communication direction module and a protocol adapter module operably coupled to one another. The communication direction module detects a direction of communication between the communicating devices using physical layer parameters of the communication protocols, and establishes communication there-between, using a sampling clock. The protocol adapter module adapts the communication direction module to the communication protocol in use, by generating the sampling clock.

Adaptive repeater for industrial communication

A power harvesting system is provided for harvesting power from a current carrying conductor for powering a load. The power harvesting system includes an energy conversion module at least partially disposable on the current carrying conductor, and an impedance regulation module coupled to the energy conversion module. The energy conversion module couples an induced voltage proportional to a line current flowing in the current carrying conductor, for powering the load. The impedance regulation module dynamically regulates impedance in the power harvesting system for controlling transfer of the power harvested using the induced voltage and the line current, to the load.

Dynamic power harvesting system

A method and a parameter estimation system are provided for controlling an electrical machine, (e.g., an induction motor), powered by a drive unit. The method and the parameter estimation system disclosed herein detect a travelling wave generated on a linking element disposed between a first connection point, which is at least one terminal of the electrical machine, and a second connection point, which is at least one terminal of the drive unit. Further, the method and the parameter estimation system disclosed herein obtain at least one of a plurality of wave characteristics associated with the travelling wave, (e.g., an amplitude, a width, a frequency, a travel time of the travelling wave). Further, the method and the parameter estimation system disclosed herein determine one or more control parameters, (e.g., an operational torque and speed), of the electrical machine based on at least one of the wave characteristics.

Methods and systems for controlling an electrical machine

Methods and electronic devices are disclosed for supplying a load with an input voltage including determining a level of a supply voltage. The method includes enabling a voltage step-down unit while disabling a voltage step-up unit when the supply voltage exceeds a first threshold voltage. The method includes enabling a voltage step-up unit while disabling a voltage step-down unit when the supply voltage is below a second threshold voltage. The electronic device includes a voltage step-up unit for stepping up the supply voltage below a first threshold, a voltage step-down unit for stepping down the supply voltage above a second threshold, and a switching unit coupled to the voltage step-up unit and the voltage step-down unit. The switching unit is configured to at least one of enable and bypass at least one of the voltage step-down unit and the voltage step-up unit based on the level of the supply voltage.

Regulating voltage supplied to a load using switching units

A dynamic impedance system deployable on a current transformer having a core and at least one winding element is provided. The dynamic impedance system includes a voltage reference module and a dynamic impedance module operably connected to one another. The voltage reference module defines a voltage threshold for regulating an output voltage of the current transformer. The dynamic impedance module regulates the output voltage based on the voltage threshold defined by the voltage reference module to maintain flux induced in the current transformer, thereby avoiding core saturation of the current transformer and enhancing accuracy of measurements.
