Filed: 1996-12-16
Granted: 1998-07-10
Abstract: FIELD: special-purpose power supplies for gaseous-discharge panels to produce controlled images. SUBSTANCE: process involves recharging of plasma display capacitor. First, it is recharged by pulse of resonant recharging current through controlled charge- discharge circuit set up of series-connected inductance coil, switch, and diode with second switch and opposing diode connected in parallel to them, then by pulse of current compensating for voltage amplitude reduction during recharge half-cycle. Recharging takes place through nonlinear inductance coil; during most of recharge half-cycle, inductance coil core is saturated and during remaining part of half-cycle chosen to be equal to double turn-on time of diodes core is not saturated. Nonlinear inductance coil provides for raising voltage across capacitor at end of transient period thereby partially compensating for poor diode characteristics.
