Patent JP-H04137978-A (JP)
Title: Clip circuit
Inventor: KAWAGUCHI TOSHIHARU
IPC: H04N5/243
Filed: 1990-09-28
Abstract: PURPOSE:To prevent unbalanced high and low clipping by adopting an NPN transistor(TR) for a TR clipping a high level and a low level. CONSTITUTION:This circuit differs from a conventional circuit in a point that an NPN TR Q4 is employed for a high level clip TR. That is, an edge signal whose reference transmission level is based on a reference voltage Vref is fed as an output of a clamped amplifier 2 to a clip output terminal 3. When the level of the edge signal exceeds a high clip level with respect to the reference voltage Vref, the TR Q4 is turned on. Since an output of an operational amplifier A3 of voltage follower constitution connects to the emitter of the Tr Q4, the emitter is regarded to have a sufficiently low impedance. In this case, when the output impedance of the clamped amplifier 2 is set sufficiently higher than the impedance when the TR Q4 is turned on, the high level clip is implemented in a similar way to a conventional circuit. Moreover, the low level clipping is entirely the same as that of a conventional circuit.

Title: Driving circuit for semiconductor power switching element
Inventor: YUZURIHARA ITSUO
IPC: H03K17/687
Filed: 1986-10-30
Abstract: PURPOSE:To bring the rate of rise of voltage applied to a semiconductor switching element into a permissible value or below by connecting a control semiconductor switching element turned on during the off-period of an input side semiconductor switching element to a short-circuited winding of a drive transformer. CONSTITUTION:Output signals B, C from a switching IC1 are supplied to metal oxide film field effect TR MOSFETs 2, 3 and a waveform D is formed by a NAND gate element 20, then supplied to a MOSFET 21, which is turned on only when both the MOSFETs 2, 3 are turned off, and turned off in other periods. Since any of the MOSFETs 2, 3 or 21 is turned on during all periods of t1-t3, the internal impedance of the voltage E3 induced to the output winding of the drive transformer shows a very low impedance. As a result, all problems such as the oscillating waveform or malfunction of the MOSFETs due to the induced voltage caused by a displacement commutation between the drain and gate of the MOSFETs 6-9 are all solved.
