Patent JP-H05207753-A (JP)
Title: Control method for clamped neutral point type inverter
Inventor: MIURA KAZUTOSHI
IPC: H02M7/483
Filed: 1992-01-24
Abstract: PURPOSE:To eliminate uncontrollable region by outputting a control pulse depending on the comparison results between a set time and the control pulse added with an error time and then adding the error time to a next control pulse thereby ensuring minimum ON time for the element even if the input signal is low and producing an output voltage proportional to the input signal. CONSTITUTION:A voltage command value eu is compared with outputs X, Y from triangular wave generators TRG-X, TRG-Y through comparators COM1, COM2 to produce control pulses Pti1, Pti2 which are then fed to control circuits CNEW 1, CNEW 2. A pulse generating circuit TCON 1 generates a pulse Pton which is synchronous with the input pulse Pti1 and an arithmetic circuit CAL performs logical operation on the pulse Pton to produce output signals S1, S2. The CNEW 2 also produces output signals S3, S4 through similar operation. The arithmetic circuit CAL produces no output if the pulse width of the pulse Pti1 added with an error time is shorter than a set time and that value is stored as an error time which is subsequently added to a control pulse.

Title: Sense amplifier
Inventor: FUJIWARA HIDEO
IPC: G11C16/06
Filed: 1995-01-27
Abstract: PURPOSE: To prevent a break-through current and to attain reduction of the power consumption by having a fifth channel transistor which is in OFF state only when a sense amplifier operates and a sixth channel transistor which is in ON state only when the sense amplifier operates. CONSTITUTION: The sense amplifier 100 for readout and the sense amplifier 200 for comparison are of a clock synchronization type and become active only when a control signal delivered from a control signal generating circuit is at a low level. During a period when the control signal is at a high level, Tr 104 and Tr 105 are in an OFF state and Tr 106 in ON state and a voltage V of a bit line 152 lowers to a low level (predischarge). Accordingly, Tr 107 comes to be in OFF state and, therefore, a break-through current does not flow at all. In the case where the control signal is at the low level and a memory cell 151 is OFF, the voltage V of the bit line 152 rises gradually and becomes equal to a value obtained by subtraction of a threshold of Tr 101. Accordingly, the bit line 152 can be charged in a short time.
