On the circuit diagram below show us a schematic which is used to set the speed of a low-power induction motor, such as those which can be found in fan applications. Noise coming from TRIAC commutations can be filtered using capacitors C1, C2 and C4. C2 has to be from X2 technology, whereas C1 and C4 capacitors have to be […]
Read moreThis temperature controller employs an LM135/235/335 temperature sensor, can be used to keep small environment warm or hot. Here is the schematic diagram: LM311 is used as comparator, to detect if the voltage at sensor pin (the inverting input) goes higher than the reference pin (the non-inverting pin). If this condition is detected, the comparator will switch off the heater […]

This diagram tells us about how to use L200 device for the speed control of permanent magnet motors. By means of R1 and R2, we can obtain the desired speed, proportional to the voltage at the terminal of the motor. Vm= Vref (1+R2/R1) We can use this following equation to obtain better compensation of the internal motor resistance, which is […]

This is higher input or output for L200 voltage regulator circuit. This circuit is designed to solve the problem that occurs when the input or output voltages are higher than the device can produce. This circuit uses the external components. Here is the circuit : The transistor is used to absorb the excess voltage when there are high input voltage. […]
