Title: Lead frame
Inventor: AOI YASUNORI
IPC: H01L23/50
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To avoid deforming leads connected to a support frame near bridges in brazing a lead frame having slits at the support frame and the bridges cross- coupling them. SOLUTION: One face of a bridge 9 is bent down and its thickness is reduced to about a half the thickness of other part, thereby reducing the strength of the bridge 9. In mounting on a package body by brazing, etc., the bridge can be easily deformed by an axial stress caused in a lead 3 due to the thermal expansion difference between a metal making the lead frame and insulation board making a package and this is effective for avoiding deforming the lead 3.

Abstract: PURPOSE:To reduce the overcurrent withstand strength of a rectifier by invaliding a current control due to the input current of an inverter when the inverter is overloaded and raising the voltage of a DC intermediate circuit from a floating charging voltage to a uniform charging voltage. CONSTITUTION:When the output current of a thyristor inverter 18 becomes the prescribed value or higher, an overload detector 42 is operated, a normally closed contact 34 is opened to interrupt a detection current signal from a DC current transformer 30, thereby invaliding a current control system for controlling a thyristor rectifier 10, thereby eliminating the limit of the output current of the rectifier 10. Simultaneously, a normally open contact 24 is closed, and a uniformly charging voltage setter 22 is connected to a voltage control system. Accordingly, the voltage of a DC intermediate circuit is raised to the uniform charging voltage which is higher by 10% than the floating charging voltage from a battery 16. Thus, since the DC voltage decreases, the overcurrent withstand strength of the rectifier 10 can be decreased.
