Single Phase vs Three Phase Power Explained

Single Phase Power. Able to supply ample power for most smaller customers, including homes and small, non-industrial businesses. Adequate for running motors up to about 5 horsepower; a single phase motor draws significantly more current than the equivalent 3 phase motor, making 3 phase power a more efficient choice for industrial applications.

what is a cycloconverter

3. Cycloconverter A device which converts input power at one frequency to output power at different frequency in a single stage is known as cycloconverter. A cycloconverter is basically of two types. 1.Step-down cycloconverter In this type of cycloconverter the output frequency f. o. is less than the supply frequency f. s. 2.Step-up cycloconverter.

Induction Heating using Cycloconverter
