This is a circuit of Bi-Directional Motor Drive with Speed Control. This circuit is designed to replace the conventional drivers. The component cost can be reduced and efficiency will increase if we use this circuit. Here is the schematic diagram of the circuit: This circuit include all required circuitry to modulate two bi-directional pulse train outputs in proportion to the […]
Read moreTypical circuit for welding equipment shown on the following circuit diagram. Turn on delay can be controlled accurately with Potentiometer P2. We can discharge C1 at each line zero voltage using DB1 diode bridge and R6-R7 resistors. The voltage charge will be reset at each new half line cycle and the turn-on delay will be maintained the same. Through both […]

We can use this circuit diagram to adjust the speed of a low-power induction motor, such as those which can be found in fan application. The function of capacitors C1, C2 and C4 is to filter the noise coming from TRIAC commutations. X2 technology is used for C2 capacitor whereas Y2 technology is used for C1 and C4 capacitors. Here’s […]

A step-down circuit used to approximately divide by two the rms voltage between the line input and the inductive load (L1) is shown on circuit diagram below. A turn-on delay of approximately 7 ms is provided by C2 and R3. We can discharge C2 at each line zero voltage using diode bridge, with diodes D1 and D2 and R2 resistor. […]
Read moreThis is a Ohm’s Law video tutorial. This video explains how to understand the Ohm’s Law. There are three main parameter of Ohm’s Law, they are voltage, current flows and resistances. Voltage is defined by V, current flows is defined by I and resistance is defined by R. In this video, the triangle of Ohm’s Law which is used to […]
Read moreThis is Electrical Voltage, Current and Resistance video tutorial. This video tells about the rules of the voltage, current and resistance. Voltage is the difference in energy level, the current is how many electrons are flowing and resistance opposes the flow of electrons. Unit of voltage is volt, the unit of current is amperes (amp), and the unit of resistance […]
Read moreThis is video about series and parallel circuit. This video shows the different between series and parallel circuits. This Video also explains how the series and parallel circuits work. In the series circuit, the voltage is divided by amount of the lamp. When we pull out one lamp in the series circuit, all the lamp will turn off because there […]
