Title: Auxiliary power supply device for electric vehicle
Inventor: AISAKA TORU
IPC: B60L1/00
Filed: 1988-12-05
Abstract: PURPOSE:To maintain an output voltage substantially constant and to reduce the number of components and size by providing gain switching means for maintaining the output voltage of a transformer with taps constant, and controlling the phase of an inverter with a full-bridge structure. CONSTITUTION:The intermediate tap side and a winding end sides of a transformer 7 are switched by a converter 5 in response to a rated trolley wire voltage detected by a voltage detector 21. A full-bridge inverter 14 is composed of four sets of switching elements 14A - 14D, and the gain of a phase control circuit 20 is so switched as to generate the same rated voltage at the secondary side of the transformer 7 in response to a trolley wire voltage. Thus, the output voltage of the inverter 14 can be kept substantially constant. The number of components can be reduced to 1/2 - 1/4 of that of the conventional one, and its size can be reduced.

Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To shorten a test time and simplify a test by generating a plurality of memory macros and a macro ID for identifying the plurality of memory macros in one chip outside the plurality of memory macros, and electrically connecting one of the plurality of memory macros to an output pad. SOLUTION: At a selected memory macro, MEn=0 is input to a macro output control circuit 48 and an 8-bit output signal which is a direct selection of TDO(0-7) is output as an output signal DTDO(0-7) of the memory macro. At a non selected memory macro, MEn=1 is input to the macro output control circuit 48, and therefore the output signal DTDO(0-7) of the non selected memory macro is fixed to '1' irrespective of the 8-bit output signal TDO(0-7). The signal of '1' or '0' is fed to a logic part from the selected memory macro, and the output signal of '1' is fed from the non selected memory macro.

The drain potential of FETM1 in a lower stage is set as the gate bias of FETM3 for constant current source and the drain potential of FETM2 in a higher stage is set as the gate bias levels of the differential pair M4 and M5. When a prescribed relation is established between the ratio of size of M1 and M2 and the ratio of size between M3 and M4+M5, a drain bias Vd of M1 and that of M3 are equal and M1 is diode-connected. Thus, the drain bias Vd and gate bias Vg are equal. Even if temperature fluctuations exist, M3 operates in the saturated state at all time, while keeping a prescribed voltage margin.
