Beschreibung
Zusammenfassung:	FIELD: electrical engineering. SUBSTANCE: proposed gear incorporates converter of current to proportional voltage, converter of alternating voltage to direct one, starter, output unit formed by summing element and voltage-to- frequency converter that includes generator of current proportional to input voltage, integrating capacitor, discharge key of capacitor, comparator, isolation diodes, scaling resistors. EFFECT: simplified design of gear thanks to exclusion of usage of squarer. 1 dwg
