5.Converters and Inverters
6.◎Converters
7.These are devices that transform single-phase and three-phase AC into DC using semiconductor elements such as diodes, silicon controlled rectifiers, or transistors. They are commonly referred to as rectifiers or converters.
8.Larger DC motors with an output of 30kW are typically driven by converters, while smaller DC motors also have instances where they are operated by converters.
9.◎Inverters
10.On the other hand, inverters are devices that convert DC to three-phase AC.
11.Modern refrigerators and indoor air conditioners utilize inverters to power motors and drive compressors.
12.For home air conditioners, converters first change single-phase AC to DC before inverters then convert it to three-phase AC in order to operate the motors. Although this may seem complex, there are objective reasons for its implementation.
