What Is a Phase Converter?
A phase converter is a device designed to convert electrical power from single-phase to polyphase, or from polyphase to single-phase. The term ‘phase’ in this context refers to a physical quantity that characterizes the progression of periodic waves or vibrations in time or space. In a single-phase system, power is supplied through a single alternating current (AC) wave, represented by one waveform. Conversely, a polyphase system uses multiple AC waves — typically three — simultaneously, which increases the efficiency of power transmission.
Phase converters adjust the phase of the input signal based on the control voltage, allowing control over the temporal position and waveform of the signal. These converters typically utilize control elements such as variable capacitors or resistors. By adjusting these elements, the output signal’s phase can be customized to meet specific requirements, making phase converters a versatile tool in various electrical applications.
