Discussion Overview

The discussion revolves around the conversion of electrical frequency, specifically the feasibility of changing supply frequencies to 15Hz or other specified frequencies in the context of Indo-Pak and USA power systems, which operate at 50Hz and 60Hz respectively. The conversation includes theoretical and practical approaches to frequency conversion.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant inquires about devices or circuits capable of changing frequency to 15Hz, seeking elaboration on the topic.
  • Another participant suggests using a motor-generator combination or rectifying input power followed by an inverter to achieve the desired frequency output.
  • A different participant raises a question about the potential drawbacks of using 15Hz as a power waveform.
  • Another contribution mentions the concept of a "Power Mixer" for mixing and filtering power, presented in a somewhat humorous context.
  • A participant references dielectric heating as an example of frequency application, noting that voltages of about 20KV at frequencies of 10 to 30MHz are used, and questions how frequency is changed in that context.
  • One participant proposes the use of a variable frequency inverter, indicating that such devices can generate a range of frequencies, typically from 0 to 120Hz.

Areas of Agreement / Disagreement

Participants present multiple approaches and ideas regarding frequency conversion, but there is no consensus on a single method or the implications of using 15Hz as a frequency. The discussion remains open with various viewpoints and suggestions.

Contextual Notes

Some contributions involve assumptions about the feasibility and practicality of different methods for frequency conversion, and there are unresolved questions regarding the implications of using specific frequencies.

As we know in indo-pak our home supply voltages frequency is 50 Hz. And in USA it's 60Hz. Is there any device/circuit that can change frequency to 15Hz or any other according to our requirements.
Please Elaborate :confused:

You can use a motor-generator combination, or rectify the input power and use an inverter to make your new output power waveform.

Quiz Question -- why would 15Hz be a bad choice for a power waveform?
 
How much power? You could mix and filter. That would be way cool (in a Rube Goldberg sort of way) -- a Power Mixer! :approve:
 
here is an example in "Dielectric heating" which is used to heat insulators like wood, plastic, ceramics etc which cannot be heated easily and uniformly by another method.
In this method we apply voltages of about 20KV at frequency of 10 to 30Mhz. Now how they change frequency. One method may be changing the speed of generator but any other one!
