Advantages & disadvantages of switch mode power supply (SMPS)
Following are the advantages of switch mode power supply (SMPS) are, The switch mode power supply has a smaller in size. The SMPS has light weight. It has a better power efficiency typically 60 to 70 percent.
What is voltage regulator?
The voltage regulator is a regulator which is designed to automatically convert voltage into a lower, direct current (DC) and constant voltage. It is mainly used to maintain a constant voltage level. A fluctuating DC voltage may
What is an Oscillator?
The oscillator circuit is made up of two reactive elements inductor and capacitor. It is also known as tank circuit. In electronic circuit it produces a periodic, oscillating electronic signal often a sine wave or a square
What is a filter?
A filter circuit may be defined as an electrical circuit which is minimized the undesirable AC component from the rectifier output and allows the DC component to reach the load. The filter is used to minimize the
Applications of inductors
