Device description

AC/AC Converter

AC converter that changes voltage level, frequency, phase characteristics, or other properties of an AC output.

An AC/AC converter changes characteristics of an AC voltage without producing DC voltage as the final output.

Depending on design, it may change output-voltage amplitude, frequency, phase count, or phase angle. Some models synchronize the output with the input source, while others can operate as frequency converters with independently generated output frequency.

For multiphase devices, phase-connection arrangement, neutral availability, preservation of phase sequence, and permissible output-voltage and load unbalance are important.

Phase-controlled models regulate output by changing the conduction or firing angle of power devices.

Selection criteria include input and output ranges, rated apparent power, frequency, output waveform and THD, phase count, synchronization, phase-angle control, permissible capacitive load, and electrical isolation.
