By analyzing the specific needs relative to the application, the user can make an educated choice regarding the converter type that is best for their specific application. 10,000 to 20,000 Hrs. Some environmental objections, e.g., audible noise, unit weight, space factor, etc. Fewer environmental objections, e.g., generally quieter, lighter weight, etc. Input to the converter s motor has lagging power factor that increases with load.
Input current has high crest factor that also causes leading power factor that increases with load.
Harmonic distortion and noise on the input power is not passed to the output Harmonic distortion and noise on the input power is not normally passed to the output, some high frequency noise may be passed to output. Overloads generally cause voltage reduction but not large waveform distortion Can source overloads for generally shorter periods of time, depends upon capacitive storage in unit. Overloads may cause a sharp rise in distortion. Converters Rotary power frequency converters can be further categorized as Belt Driven, Coupled Inline and Single Shaft, each of which have features and characteristics that make them suited for specific applications. The next few sections describe each of the types and their characteristics.
