Title: Uninterruptible ac power supply
Inventor: YAMAGUCHI MASAHIDE
IPC: H02J9/06
Filed: 1989-04-25
Abstract: PURPOSE:To reduce the size and the cost of an uninterruptible AC power supply by changing the jointing positions of switches. CONSTITUTION:When a battery 6 is discharged perfectly and an inverter 5 is stopped, power is fed from an AC power supply 7 through a switch 1 to a load 8. If a switch 3 is turned OFF and a switch 2 is turned ON, at this time, the battery 6 can be charged through a reactor 4 by controlling the phase difference of the AC power supply 7. Although AC side voltage is lower than the steady state voltage because DC side voltage of the inverter 5 remains low until the battery 6 is charged to some level, no trouble occurs on the load 8 because the switch 3 is turned OFF. AC voltage of the inverter 5 goes to steady state level when the battery 6 is charged to some level, and steady state operation takes place immediately upon turn OFF of the switch 1 and turn ON of the switch 3. At this time, switching of control of the inverter 5 is not required.

Abstract: PROBLEM TO BE SOLVED: To provide the malfunction prevention circuit for an integrated circuit. SOLUTION: In the case that a clock ck transits from, e.g. 'L' to 'H', a logic circuit including a logic circuit 33 is operated simultaneously, and a peak is produced in a power supply current flowing from a power supply level Vdd to ground. Thus, a voltage drop is produced in each power supply pattern connecting power supply input terminals VDD,VSS and power supply lines 31,32 resulting that power supply levels Vddi, Vssi of the power supply lines 31,32 are fluctuated. In this case, an 'H' level of an output signal S211 of a buffer circuit 211 in the malfunction prevention circuit 201 is higher than the power supply level Vddi and the level 'L' is lower than the power supply level Vssi.  Then diodes 221 , 231 become conductive, a current is supplied from the buffer circuit 211 to the power supply lines 31, 32, resulting in the voltage between the power supply level Vddi and the power supply level Vssi being kept to a normal operating voltage of each logic circuit.
