Frequency conversion is required when the voltage and frequency available does not match the equipment being powered. The most common frequencies are 50Hz, 60Hz, and 400Hz with the less common being 25Hz and 100Hz. With the globalization of the world’s economies intensifying, the need for frequency conversion is increasing as multinationals from 60Hz countries are doing more business in 50Hz countries and vice-versa.

Utilizing experience in the 400Hz industry and from early main-frames, PS&C offers two technologies to solve this power Frequency Conversion problem; static (solid state) frequency converters and rotary (Motor-Generator) frequency converters. There are several factors which will help identify which frequency conversion solution is right for your project. PS&C’s technically versed applications group will help you make an assessment of your application and select the best solution for your specific requirement.
