In general, the word voltage converter is the name given to a device that acts as a switch in one location to control the voltage of a device in another location through a power outlet. Most electrical outlets around the world that produce single-phase alternating current supply either 100 to 125 volts or 210 to 230 volts. The purpose of a voltage converter is to convert voltage from 110 volts to 220 volts and from 220 volts to 110 volts. Both tasks can also be done with some voltage converters.
Voltage converters are usually always sold with a plug on the end. Physical compatibility also comes with plugs.
There are many ways to convert voltage. Transformers are used to step down or step up the alternating voltage. Voltage converters used in small electronic devices typically have transformers that drop smaller voltages, such as 24-v-to-230-v-converters. Create a full-wave rectifier that converts alternating current to direct current (DC). Flattening the waves is done with a few additional components. Few components contain only a transformer in an external power supply. That power supply comes with additional power from gadgets or rectifiers.
Voltage converters sold for automotive use have DC outlets of 12 volts. Voltage converters do not necessarily come with transformers. In many cases, a zener diode is used instead of a transformer to lower the DC voltage with huge power losses. To convert alternating current, a low DC voltage must be converted to a high voltage. The use of a transformer is made for stepping up the voltage. Conditioning circuits and rectifiers are used to convert AC to DC.
Two types of voltage transformers are available: step-up and step-down voltage transformers. The conversion of the step-up transformer is from 110 volts to 230 volts. The conversion of the step-down transformer is from 230 volts to 110 volts. Many transformers convert either way. voltage converters and transformers.
