Title:
POWER SUPPLY CIRCUIT BOARD, POWER SUPPLY CIRCUIT, POWER CONVERSION DEVICE, AND ERRONEOUS MOUNTING DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/029861
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power supply circuit board capable of being applied to AC power supplies having different voltages and different numbers of phases without requiring an additional member on the same board.
The power supply circuit board (50a) has: first, second, and third AC terminals (L1, L2, L3) to which a three-phase or single-phase AC voltage is applied; first and second DC terminals (5, 6) for outputting a DC voltage generated by a rectifier circuit; first and second series connection portions (41a, 43a) having positive electrode terminals (21a, 31a) and negative electrode terminals (22a, 32a); and first and second parallel connection portions (42a, 44a) having positive electrode terminals (23a, 33a) and negative electrode terminals (24a, 34a). The positive electrode terminals (21a, 23a, 33a) are electrically connected to the first DC terminal (5). The negative electrode terminals (24a, 32a, 34a) are electrically connected to the second DC terminals (6). The negative electrode terminal (22a) and the positive electrode terminal (31a) are electrically connected to the third AC terminal (L3).
