 Difference between Converter and Inverter

Post by Suman Majhi

Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, invertersconvert direct current (DC) to alternating current (AC).

Applications

Converters are used to convert AC power to DC power. Virtually all the electronic devices require converters. They are also used to detect amplitude modulated radio signals. They are also used to supply polarized voltage for welding. Converters can be used for DC-DC conversion. Here, inverter converts DC to AC, then a transformer is used to convert it back into DC.


Inverters are used to convert DC electricity from sources like solar panels, batteries or fuel cells to AC electricity. Micro-inverters are used to convert DC power from solar panels to AC for the electric grid. UPS or Uninterrupted power service uses inverter to supply AC power when main power is not available. It is also used for induction heating.

What is Electrical Drive? Types of electrical drives? Electrical Drive: Whenever the term electric motor or electrical generator is used, we tend to think that the speed of rotation of these machines is totally controlled only by the applied voltage and frequency of the source current. But the speed of rotation of an electrical machine can be controlled precisely also by implementing the concept of drive. The main advantage of this concept is, the motion control is easily optimized with the help of drive. In very simple words, the systems which control the motion of the electrical machines, are known as electrical drives. A typical drive system is assembled with a electric motor (may be several) and a sophisticated control system that controls the rotation of the motor shaft. Now days, this control can be done easily with the help of software. So, the controlling becomes more and more accurate and this concept of drive also provides the ease of use. This drive system is widel

How to get pure sinusoidal AC output from DC input using PWM inverter By Suman Majhi What is Inverter? Inverter is an electrical equipment which is used to convert dc supply into AC supply. there are two different types of inverter used in the electrical field. they are given below, 1) square wave inverter 2) sine wave inverter here we will going to see about how to convert pure dc into pure ac sinusoidal wave. these process involved different steps. so we will briefly discuss about each steps. Square wave inverter Generally all inverter produced square wave ac output only. because square wave inverter is not required any addition component to convert ac from dc supply. even cost wise its really cheaper then pure sine wave inverter. working of square wave inverter The working of square wave inverter is  explained through below diagram. let us consider full bridge rectifier, S1,S2,S3 and S4 are switches and resistance is load. let switch s1 & s2 keep it on and switch s3 & s4

Basic Electrical Theory  Electrical charges:-   Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs (C).  • The charge e on one electron is negative and equal in magnitude to 1.602 × 10-19 C which is called as electronic charge. The charges that occur in nature are integral multiples of the electronic charge.   Electrical Current:-  Electric current i = dq/dt. The unit of ampere can be derived as 1 A = 1C/s. • A direct current (dc) is a current that remains constant with time. • An alternating current (ac) is a current that varies sinusoidally with time.   Example 1  A conductor has a constant current of 5 A. How many electrons pass a fixed point on the conductor in one minute? Solution Total no. of charges pass in 1 min is given by 5 A = (5 C/s)(60 s/min) = 300 C/min Electric Voltage:- • Voltage (or potential difference) is the energy required to move a unit charge through an element, measured in volts (V
