Closed loop or servo system has the ability to stabilize the controlled plant at a specified operating condition. The plant, the controlled sub-system, can be any form of controllable system. In motor control system, the plant is off course a motor. The basic principle of automatic control mechanism in motor control is by monitoring the real speed of the motor, […]
Read moreRS 232 line to 5 V converter circuit schematic diagram is shown on the following figure. The MAX680 is normally used as a charge pump voltage converter. This converter can convert +5 V to ±10V. The MAX 680 works in reverse in this circuit. That means MAX 680 converter the RS 232 signal levels to a lower voltage. The output […]

The silicon controlled rectifier (S.C.R.) is called as the thyristor. It is like a diode, when the cathode is negative with respect to the anode, the current flowing from cathode to anode. But, the difference of thyristor and diode is the current will flow then the cathode is also negative with respect to the gate. Here is the schematic diagram […]

The circuit below is configured as a comparator. A fixed reference voltage at the non inverting input is provided by R1 and R2. The inverting input voltage is set by the other two resistor. The output goes to minus 12 volts and the buzzer is energized if the voltage at the inverting input rises above the reference voltage. By swapping […]
