... Configuring the Step-Down Output (VSD) The input to the step-down converter (PVSD) on the EV kit comes connected to VSU, but the connection can be changed to either BATT or VM. To use BATT as the input to the step-down converter, cut the trace shorting JU11 and short the pads of JU10. To use VM as t ...

... Large induction motors, which are widely used in industries, can also cause voltage sags [4]. In this case, voltage sags are characterized by the nonrectangular shape caused by the increase of the motor starting current. In this paper, the start of an induction motor is also simulated to study the s ...

Current mirror

A current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being 'copied' can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well or it is a current-controlled current source (CCCS). The current mirror is used to provide bias currents and active loads to circuits. It can also be used to model a more realistic current source (since ideal current sources don't exist).The circuit topology covered here is one that appears in many monolithic ICs. It is a Widlar mirror without an emitter degeneration resistor in the follower (output) transistor. This topology can only be done in an IC as the matching has to be extremely close and cannot be achieved with discretes.Another topology is the Wilson mirror. The Wilson mirror solves the Early effect voltage problem in his design.
