Constant current constant voltage

This research investigates integrated drive topologies for Switched Reluctance Motors (SRMs). During the research project, three new power electronic topologies are proposed and simulated via extensive simulations in finite element modelling software (Maxwell) and MATLAB/Simulink.

Typical dynamic responses are also shown. The motor is initially at standstill and at no load when a step command in speed is applied; when steady-state conditions are reached, a reversal of speed is commanded followed by a step load application. The system is highly nonlinear due to the introduction of saturation needed to limit both the current delivered and the voltage applied to the motor.

VOLTAGE REGULATION A voltage regulator circuit automatically maintains the output voltage of a power supply constant, regardless of - a change in the load - a change in the source voltage ZENER DIODES The simplest of all voltage regulators is the zener diode voltage regulator. A zener diode is a special diode that p is optimized for operation in the g breakdown region. ZENER DIODE CIRCUIT The zener diode is typically connected reverse biased, in parallel with the load. Resistor Rs limits current to zener.

DC drives are widely used in applications that require regeneration, precise speed control, dynamic performance, and constant torque over wide speed ranges. The Mentor II delivers the universal DC drive solution. Simple stand-alone applications are easily configured to control motor speed, voltage or current using standard internal settings. Set-up is convenient using the drive keypad, CTKP remote keypad, or MentorSoft, a Windows based drive configuration tool. The Mentor II has extensive diagnostic and communication abilities that enhance system reliability.
