The circuit consists of four thyristor switches (T1, T2, T3, T4), ISis the input source current which is constant, and you can see that there is no any anti-parallel diode is connected. The constant current is provided by connecting voltage sources in series with large inductance. We know...
PURPOSE: Current source circuit is provided to realize a current source circuit that operates by a power supply voltage lower than that for known current source circuit. CONSTITUTION: FIG. 2 shows a block diagram of an embodiment of a current source circuit according to the present invention. ...
The device in the circuit diagram can be any electronic circuit or device such as a microcontroller, FPGA, CPLD, logic circuit, etc. Current Sourcing When a load is connected to a device so that the device supplies current to the load (sources current) then the configuration is said to be...

So, it is clear that theresistordecides the current flow in avoltage sourcecircuit or it performs as a simplevoltage to current converter(i.e. a V to I converter) for a linear circuit. The circuit diagram below shows a resistor acting as a simple voltage tocurrentconverter. In this diagra...
Programmable current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source. The term current sink is sometimes used for sources fed from a negative voltage sup...
Combining this expression with Equation 28.1, we see that IR Ir (28.2) a b c d Solving for the current gives (b) Figure 28.2 (a) Circuit diagram I R r (28.3) of a source of emf (in this case, a battery), of internal resistance r, This equation shows that the current in this ...
(carrying the permanent magnets) are shown to illustrate the rotation of the motor shaft. In the first diagram, only two phases (V and W) are energized from the power source, phase U is not. The strong magnetic flux of the North pole of the permanent magnet and the magnetic field ...
The MOSFET Constant-Current Source Circuit Here is the basic MOSFET constant-current source: It’s surprisingly simple, in my opinion—two NMOS transistors and a resistor. Let’s look at how this circuit works. As you can see, the drain of Q1 is shorted to its gate. This means that VG...
