In Indo-Pak, the standard power supply frequency is 50Hz, while in the USA it is 60Hz, leading to inquiries about converting frequencies to specific values like 15Hz. Solutions include using a motor-generator combination or employing a variable frequency inverter, which can generate a range of frequencies, typically from 0 to 120Hz. The discussion highlights that while 15Hz can be achieved, it may not be ideal for power applications due to potential inefficiencies. Additionally, dielectric heating techniques utilize high frequencies (10 to 30MHz) for specific heating applications, showcasing the versatility of frequency manipulation. Overall, various methods exist for frequency conversion, each with its own applications and limitations.
