I remember when I started to study matlab I was searching for matlab control design step by step tutorials but I have not seen any. Self studying is not easy, it took me sometimes to learn and get what I want. However, we will not having the same experience. I am about to share to you matlab control design step

Charging and Discharging Capacitive Circuits Detailed Explanation
Charging and Discharging Capacitive Circuits The voltage on a circuit having capacitors will not immediately go to its settling state unlike purely resistive circuits. When a potential difference is applied to an RC circuit the like of Figure 31 below and then S1 is closed, the voltage across the capacitor will exponentially rises from zero to its final value. At
READFuse Electrical Parameters Explanation
Fuse is a very simple electrical part and yet needs to be properly selected. Its role in the circuit is very important actually. Selecting a right fuse starts with a good understanding on fuse electrical parameters. There are some important fuse electrical parameters to consider. These are the Current Rating, Ampere Square Seconds, Breaking Capacity and Voltage Rating. Fuse Electrical Parameters Explanation 1.

Circuit Analysis Methods
There are several circuit analysis methods. In this article I will discuss the most common. In the proceeding discussion I will just use a resistor as an example but in actual application it is not limited to it. Popular Circuit Analysis Methods 1. Ohm’s Law Ohm’s law is very popular in resistive circuit. It states that the current flowing through

Fuse Operation and Principle
In this article I will discuss Fuse Operation and Principle. A fuse is a simple electrical part which consists of a wire and terminals on each end. It is plainly a passive device which protects the circuit in the event of a large current. When this happens, the fuse element will open and the circuit will become discontinuous. Fuse operation

Factors Affecting Current Transfer Ratio of Optocoupler
Current transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector current to the forward current. Current transfer ratio is popular by its abbreviation CTR. CTR is simply the measure of the optocoupler’s transfer efficiency. If we recall the basics, optocoupler is a semiconductor device with a light source and a detector.

MOSFET Advantages Over BJT in Switching Converters
Way back several years ago, power supply designers and engineers are continuously searching for innovation. Long time ago what is available is only the linear type power supply. A linear power supply will consume a lot of power in order to provide regulation. This huge power consumption sacrifices the efficiency of the power supply. Try to imagine if you are
READComprehensive Relay Kickback Voltage Analysis
Relay is made up of two elements; the coil and the contact. The coil needs to be energized so that the contact will change state. For detailed analysis on how to drive the relay coil for it to energize read this. In this topic we will jump directly to relay kickback voltage analysis. As mentioned, relay has a coil. This coil

Opto Coupler CTR Explanation
Opto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time of understanding what is it. Current transfer ratio or commonly known as CTR is the ratio of the collector current to the forward current of an optocoupler. It is synonymous to a current gain of a bipolar junction transistor. If this is the first

MOSFET Efficiency Factors for Switching Converters
We will discuss here the three main contributors of power losses of the MOSFET when used in switching converter or switch mode power supply. The main MOSFET efficiency factors are drain to source on state resistance, gate charge and the equivalent output capacitance. Drain to source on state resistance or simply RDSon has a positive temperature coefficient (increases with temperature
