Patent JP-H0855669-A (JP)
Title: Pulse corona discharge circuit
Inventor: UCHIYAMA YUJI
IPC: B01D53/50
Filed: 1994-08-17
Abstract: PURPOSE:To generate a high voltage of a narrow pulse width. CONSTITUTION:Capacitors C0, C1 are connected in parallel to power supplies E0, E1 respectively, so a supply voltage is shared by the capacitors C0, C1. While the capacity of the capacitor C0 is set at a larger value than that of the capacitor C1, the voltage of the power supply E1 is set higher than that of the power supply E0, so by closing a switch SW, a higher voltage is discharged from the capacitor C1 than that from the capacitor C0. The value of the capacitor C1 is set to resonate with the impedance between discharge electrodes 10, 12, and an inverse flow preventing diode D1 and a coil L1 are connected in parallel to the capacitor C1, so an output voltage of the capacitor C1 shows characteristics of a narrow pulse width, and of becoming flat after starting discharge. A pulse voltage of a high voltage and a narrow pulse width is thus applied between the discharge electrodes 10, 12.
