Difference between Generator and Inverter

Main Difference

Generator and Inverter are both electrically used devices. They both are different from each other in their application, function and construction. A power inverter is basically an electronic device which is used to serve the purpose of converting direct current into alternating current. The inverter is a circuitry that took DC current as an input and converts it into an AC. The inverter does not produce power. It is just fed up with DC source and its output is alternating current whereas generator is a gadget which produces electrical power as an input. whatever is the type of the generator, it always converts mechanical power into electrical power. They operate on the principle of electromagnetic induction. The fundamental principle is faraday law of electromagnetic induction which says that changing magnetic field produces an electric field and changing electric field produces a magnetic field.


invertorsA standard electrical power inverter unit or possibly a circuit demands a reasonably steady DC source of energy competent at delivering sufficient current for your designed power demands of your system. The input voltage is dependent upon the design and style and intent behind the inverter. the two main types of the inverter are power inverter and solar inverter. an inverter can certainly create and produce different waveforms some of them are, pulsed sine wave, square wave, altered sine wave pulse width modulated wave (PWM) or sine wave determined by circuit layout. For converting DC into AC, some converters are a buck converter, buck-boost converter or boost converter. The output frequency is of typical standard power alone that is 50 or 60 Hz. it can be applied in a series configuration or in a parallel configuration, depending upon the purpose of the inverter. In solar inverters, a direct current of the photovoltaic battery of the solar panel is converted into alternating current AC. which is then given directly to appliances in domestic consumers or fed to grid station on a massive scale. Three major types of solar inverters

  • Stand-alone inverters
  • Grid-tie inverters
  • Battery backup inverters

Major applications of the power inverters are in

  • Uninterruptible power supplies
  • Electric motor speed control
  • HVDC power transmission
  • Electroshock weapons
  • Electric motor speed control


generatorsBasically, there are two main types of the generators. AC generator or DC generator. A.C. power generators or even sometimes they are called as alternators are powered by exactly the same basic principles of electromagnetic induction as D.C. generators. Alternating voltage could possibly be created through revolving a coil within the magnetic field or possibly  by a spinning  magnetic field inside a fixed coil. The value associated with the voltage produced is based upon the actual range of turns within the coil, the durability of your field and the pace where the actual coil and / or magnetic field revolves. where on the other hand DC electrical generator generates direct electrical power. The two of these power generators create electrical energy, according to the exact same simple basic principle of Faraday’s law associated with electromagnetic induction. Based on that law, whenever a conductor revolves inside a magnetic field it cuts magnetic lines force, due to which an emf is actually caused within the conductor. The value of your induced emf is determined by the speed associated with a change of flux which is magnetic line force linkage together with the conductor. This particular emf may cause a current to circulate when the conductor circuit is actually closed down. Therefore, the simplest 2 important areas of an electrical generator are usually:

  • A magnetic field and
  • Conductors which usually revolves within that magnetic field.

Key Differences

  • An inverter takes the existing power and then converts it whereas generator generates the power
  • Generator converts mechanical energy into electrical energy whereas inverter just alters electrical energy
  • Inverters are automatically controlled whereas generator requires some assistance to start
  • Inverters do not produce sound during their function while generators produce noise most of the times
  • Generators are fuel dependent whereas inverter is not fuel dependent.
