Abstract: PURPOSE: A circuit for producing (+)(-) square pulse or (+) square pulse when receiving (+)(-) pulse inputs is provided to implement an inverter switching circuit proper to a large-output level not requiring DC power-source, by changing an impact wave generated from a general transformer to (+)(-) square pulse or (+)(0) square pulse. CONSTITUTION: If an input signal is an impulse, an output terminal generates a square pulse. PNP is opposite to NPN, current directions generated from two diodes are discriminated from each other. If (+) impulse is applied to an input terminal, the PNP is turned on, and an output terminal forms a square pulse. If a voltage(e) is lower than a voltage(c), the pulse signal cuts off all terminals. If (-) impulse is applied to the input terminal, the NPN is turned on, the terminal(c) is driven by (-) voltage, the PNP is cut off, thereby forming (-) square pulse.
