Rectifiers and Converters - synchronous or rotary converter
1 Answer
Rectifiers and converters are electrical devices used to change the form of electric power, typically from alternating current (AC) to direct current (DC) or vice versa. A synchronous converter and a rotary converter are both types of rotary electrical converters, but they serve different purposes and operate in distinct ways.
Synchronous Converter:
A synchronous converter is a type of rotary converter that converts alternating current (AC) to direct current (DC) or vice versa. It consists of a synchronous motor and a commutator. The synchronous motor is used to provide mechanical rotation, and the commutator converts the AC voltage to DC voltage. This device is not very common today due to the complexity of its operation and maintenance requirements.
Rotary Converter:
A rotary converter is a type of electrical machine that can convert AC power to DC power or vice versa. It's essentially a combination of a synchronous motor and a DC generator within a single housing. The rotary converter operates by using the synchronous motor to rotate and generate a rotating magnetic field. This magnetic field is then used to induce voltages in the generator part, effectively converting AC power to DC power or vice versa.
Rotary converters, including synchronous converters, were widely used in the early days of electrical power distribution when technologies like solid-state rectifiers were not as developed. However, as solid-state devices like diodes and thyristors became more efficient and reliable, they largely replaced rotary converters for most applications.
Rectifiers:
A rectifier is a device used to convert alternating current (AC) to direct current (DC). It can be implemented using various technologies, including diodes, thyristors, and more advanced semiconductor devices. Rectifiers are commonly used in power supplies for electronic devices, battery charging, and various industrial applications.
In summary, while both synchronous converters and rotary converters were once used for power conversion, they have largely been replaced by more efficient and reliable solid-state devices for most applications. Rectifiers, on the other hand, continue to be used extensively for converting AC to DC power.
