【Abstract】 A divider-digital storage oscilloscope program is proposed to monitor variation of voltage signal on thyristor from triggered to conducting in pulsed power source. Establishing lumped parameter model of resistive divider was established. The degree of influence which stray inductance,stray capacitance and longitudinal capacitance caused on the low-voltage output waveform amplitude、response time、phase error were analyzed. A simulation was analyzed by PSPICE. The new divider was developed by using glass enamel film resistor according to the result of analysis,and the voltage signal generated from capacitive Pulse Power Source is in great agreement with the new divider after theoretical analysis and experimental verification.更多还原
