And like each of those gadgets, it has its own advantages and disadvantages. The video below from Jacob Dykstra takes you through one. In the future, we could have more efficient SMPS aimed at a better converter doing the most effective conversion process.

The focus areas for designers in making SMPS efficient would be:. This time I am stuck in selecting a suitable transformer from market, the schematic diagram is given in following link as an application of U I believe that you will be the right person to discuss this regards. Please share a convenient time and number to call you for a short discussion. I have 12 v SMPS battery charger which gives out put voltage I want to out put voltage Please suggest me.

I want to know what is the theory of transformer design. Also the no of secondary turns 11 turns or 10turns. Q1 and Q2 are not given in the circuit. Thanks in advance. Good day Sir, is it possible to convert a portable mains Dell laptop charger to a DC type by replacing the AC input capacitor only.

The signal is isolated from the other section so that any sudden spikes should not affect the circuitry.

A reference voltage is given as one input along with the signal to the error amplifier which is a comparator that compares the signal with the required signal level. By controlling the chopping frequency the final voltage level is maintained.

This is controlled by comparing the inputs given to the error amplifier, whose output helps to decide whether to increase or decrease the chopping frequency. We can get a better idea on the complete functioning of SMPS by having a look at the following figure. The SMPS is mostly used where switching of voltages is not at all a problem and where efficiency of the system really matters.

There are few points which are to be noted regarding SMPS. They are. The efficiency of SMPS is high because, instead of dissipating excess power as heat, it continuously switches its input to control the output. There are many applications of SMPS. They are used in the motherboard of computers, mobile phone chargers, HVDC measurements, battery chargers, central power distribution, motor vehicles, consumer electronics, laptops, security systems, space stations, etc.

There are four main types of SMPS such as.
