Title:
THREE-PHASE AC POWER SOURCE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/159435
Kind Code:
A1
Abstract:
A three-phase AC power source apparatus (1) detects currents flowing through power distribution lines at the respective phases of a generator (3), and determines whether or not any one of the detected currents exceeds a rated current. The three-phase AC power source apparatus (1) controls switching of the respective switching elements (Q1-Q6) of a load current supply circuit (5) so as to form a current path passing through choke coils (L1, L2, L3) between a power distribution line of the phase in which the current determined to exceed the rated current flows and at least one of the power distribution lines of the other two phases.
