Title:
DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/209413
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a drive system that is equipped with an induction generator having a primary winding including a main winding and an auxiliary winding and is capable of supplying power requested by an auxiliary machine inverter even during regeneration operation in which only the auxiliary winding side is energized. The maximum current value of a power generation converter is set on the basis of the maximum output of the auxiliary winding of the induction generator and the minimum voltage of the auxiliary winding when a travel inverter does not perform a regeneration operation. The no-load current value of the induction generator is set so that the maximum current of the auxiliary winding when the travel inverter performs the regeneration operation does not exceed the maximum current of the power generation converter.
