Features of application of PBY-47 controlled vacuum switches in high-current pulsed installations

The time parameters of PBY-47 controlled vacuum spark-gap switches (CVSSs), which are high-current pulse switches that can pass pulse currents with amplitudes of up to several hundred amperes, were investigated. When using CVSSs, it is necessary to know their time parameters, such as the operation delay time and its spread (jitter). To study these parameters, a run of experiments was performed on a laboratory test bench with sinusoidal discharge-current pulses with an amplitude of 120 kA and a period of 17 μs. When multimodule power-supply systems are developed, special attention is drawn to the agreed parallel operation of the switches of discharge modules. To determine the main requirements that are imposed on the operation stability of multimodule power-supply systems, a criterion was developed that relates the inductance of the load to the inductance of discharge modules and the number of modules to such a property of the used switches as a wide range of the operating voltages.
