Abstract

The invention relates to a pulse technique and can be used in applied electronics, electrical engineering and measurement technology. The purpose of the invention — improving the reliability of the driver — is achieved by eliminating the overload of the output stages of the current switches when the polarity of the generated pulses changes. The shaper contains differentiating circuits 1, 2, inverters 3 - 5, element I-HE 6, RS-trigger 7, overload analyzer 8, differential amplifier 9, controlled current regulator 10, current amplifiers 11, 12, unsaturated current switches 13, 14 and switches 15, 16. The polarity of the generated pulses is determined by the position of the switches 15, 16, and the duration is the time interval between the control signals to the inputs of the differentiating circuits 1, 2. The elimination of critical modes when the polarity changes causes an increase in reliability. 1 il.

In the absence of overload of the output stages of the unsaturated current switches 13 and 1C, the differential current 9 controls the current mode of the controlled current regulator 10, the outputs of which generate a paraphase current signal incoming through current amplifiers 11 and 12 to the inputs of the corresponding current switches 13 and 14. Due to the fact that 9 the polarity of the generated pulses is carried out without switching voltage zheny unsaturated current power keys 13 and 14 is eliminated the possibility of occurrence of a short-term overload output stages caused nonsynchronous actuation of switching circuits. Exclusion of critical modes provides increased reliability of the driver.
