  • Simple Electronic DC Load - Codrey Electronics

    Oct 13, 2017 · In principle, basic circuit of an electronic dc load contains an op-amp that drives a power MOSFET with a current sense resistor (sometimes called as load resistor). When the external voltage to be loaded is connected to the power MOSFET, and a control voltage is set by the multi-turn potentiometer in the circuit, the op-amp buffers this and

  • Star Delta Starter Operation and Principles - Recon Electrical

    Scheme - Working Principle of Star-Delta Starter After a period of time the windings are reconfigured as delta and the motor runs normally. A dual starter connects the motor terminals directly to the power supply. Hence, the motor is subjected to the full voltage of the power supply. Consequently, high starting current flows through the motor.

    Jul 26, 2011 · The soft starter operates on a different premise. This principle is that by adjusting the voltage applied to the motor during starting, the current and torque characteristics can be limited and controlled. For induction motors, the starting torque (LRT) is approximately proportional to the square of the starting current (LRA) drawn from the line.
