抗値に等しい時。(Prior Art) Recently, pulsed power supplies with fast rise times have come into wide use as various high-voltage power supplies for elucidating discharge phenomena, lasers, electrostatic precipitators, and other applications. In particular, high voltage pulses having a rise time on the order of ns (nanoseconds) are attracting attention in relation to the progress of discharge, and expectations are increasing for a power source that satisfies this requirement. Figure 3 shows an example of a high-voltage pulse generator, "Tomioka, Koyama: Voltage and pressure effects on ns creeping discharge" (Transactions of the Institute of Electrical Engineers of Japan, Vol. 101, No. 10, P519. 1982-10). In Figure 0, which shows what is used, the high voltage pulse generator consists of a waveform shaping cable 1, a cable 2 for guiding the generated voltage to the device under test, and a trigger gap 3. 'M1 combined resistance resistor 4, voltage measurement resistor 5, high voltage DC power supply 6. It consists of a charging resistor 7, a trigger power source 8, etc. When the characteristic impedance of the waveform shaping cable 1 is equal to the resistance value of the cable 2 and the discharge resistor (R1+R2).

)=−■. Here, VO(t) represents a step wave voltage whose peak value is equal to the charging voltage, and T and L represent the propagation time and length per unit length of the cable 1.
この回路構成においては０式から明らかな様にパルスの

らなかった。- As an example, if T=4.5 ns and L=10 m, the pulse width will be 90 ns. However, in order to increase the duration of the pulse, it is necessary to increase the length of the cable in proportion to the duration. For example, the duration is 10
If it is μs, it is about 1. It can be seen that a cable of IKm is required. Also, to change the pulse width,
A cable with a length corresponding to the pulse width had to be prepared.
