Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To detect failure in the short-circuit of a switching element positively by detecting the voltage difference or the voltage ratio of the first and second input-side capacitors, and regarding the first or second switching element as abnormal for protective detection when a detected value is equal to a prescribed set area or higher.

Both voltages of the filter capacitors 7a, 7b are E/2, so that the absolute value of the difference of detected values from voltage detectors 13a, 13b become 0. When the detected voltage difference from the voltage detectors 13a, 13b is equal to a prescribed set area or higher, a control circuit 14 regards a switching element 8a or 8b as abnormal for protective detection. It is thus possible to detect failure in the short-circuit of both switching elements 8a, 8b positively.

Abstract: PURPOSE:To prevent a conductive pin from buckling, prevent cleaning solution from being left in the spaces between flanges and attain an excellent holding ability of insulating material by permitting the conductive pin to have the flange whose thickness is almost the same as the depth of the space between the rear surface of a board and the rear surface of a plate and constituting the flange of a plurality of continuous compression molded parts. CONSTITUTION:A conductive pin 1 has a flange 12 whose thickness is almost the same as the depth D of a space between the rear surface of a board 80 and the rear surface of a plate 7. Therefore, the bottom surface of the flange 12 is substantially flush with the rear surface of the plate 7. The flange 12 is constituted of three continuous compression molded parts 121-123. The flanges 12 do not have spaces therebetween allowing excellent rigidity and the pin 1 does not buckle when it is press fit to a through hole 81. Since the flanges 12 do not have the spaces therebetween, cleaning solution is not left when a substrate 8 is cleaned after the pin 1 is press fit in the through hole 81. Insulating material 63 filled between the flange 12 and an opening 70 is easily held by the compression molded parts 121-123.
