First lets talk about the difference between AC and DC not the rock group. Electricity flows in two ways: either in an alternating current AC or in a direct current DC.
The difference between AC and DC lies in the direction in which the electrons flow. AC circuits include the outlets that look identical to what is in your house. DC circuits include the 12v outlets that look like the cigarette lighter in your car. Converters are electrical devices that convert the voltage from alternating current AC to direct current DC. Some non-electronic or partially electronic devices, like rotary encoders, can be considered as ADCs.
Digital-to-analog converter DAC is a device that converts a digital code to an analog signal. Digital-to-digital converter DDC is a device which converts one type of digital data to another type of digital data. There are three types of inverters: Square wave inverter: This is a type of inverter which produces a square wave output. It consists of a DC source, four switches and the load.
The switches can withstand heavy current flow. It is the least expensive inverter but it produces low quality power. Quasi wave or Modified square wave inverters: As the name suggest, the wave form is square, and not sinus as required to have pure sine wave AC. Modified square wave has a step or dead space between the square waves. This reduces the distortion or harmonics that causes problems with electrical devices.
It works for all pure loads like lamps or heaters. It costs less and is more effective than square wave. Most of the AC products run on modified sine wave inverters since they are comparatively less expensive.
Disadvantages Disadvantages of Converters: Poor current overload capacity. The good quality Automatic regulators are more expensive than Mechanical regulators. Disadvantages of Inverters: Not ideal for inductive AC and motor loads. Sensitive electronic devices can be damaged by poor waveforms by low batteries. It should have a good source of power for re-charging. Follow Share Cite Authors. Examples of converter usage include applications in mobile equipment mobile phones and laptops , LED lighting, transport car, metro, train solar panels and production machines.
A converter is an electrical or electromechanical device purpose-built to convert specific electrical characteristics voltage, current, frequency at the input to different values at the output. Sectors and areas in which converters are used include wharf cranes, steel companies, cable manufacturers extruders , welding machines, robots, LV industrial networks chemical plants, paper factories, automobile industry , data centers and hospitals.
There are different types of converters, the operating according to different methods. For example: some converters convert AC voltage to DC voltage and vice versa.
Other possible functionalities include changing voltage level or voltage frequency. Combinations of these different transformations are also possible.
This means many options and types exist, as well as a very wide range of applications such as electrical machine control, light drives, active power filters, renewable energy conversion, energy storage systems and energy generation and distribution. Available converter power levels vary from microelectronics to high-voltage power transmission. There are also devices and methods available for converting between power systems designed for single and three-phase operation.
We can distinguish four categories of converters, based on source input voltage and output voltage. The output voltage of the converter can be a variable or fixed alternating voltage with variable or fixed frequency. This type of converter can be a single-phase or three-phase converter, depending on the supply voltage. Some of these converters can also control the magnitude of the voltage as well as frequency.
These are mainly used for adjusting the speed of AC drives and for induction heating.
