UltraVolt "C" Series High Voltage Power Supply Product Notes
•Application Note: UltraVolt "C" Series High Voltage Power Supply Product Notes
UltraVolt's "A" Series units are designed for DC-bias applications with feedback compensation optimized for dynamic loading. Multiple tuned and untuned LC and RC filters provide low ripple without a need for external capacitors. "A" Series units are applicable to low-speed, capacitorcharging applications. When calculating Trise, the output charge current available is 66% of rated lout and capacitance-to-charge should have the "A" Series unit's internal capacitance added.
UltraVolt's "C" Series units are designed specifically for pulsed loads and high-speed charging of small and large capacitive loads. DC and AC feedback loops are compensated to provide fast rise time with low overshoot. Current-limit circuits are enhanced to get in and out of limit as fast as possible to maintain high average charge currents while protecting the high-voltage power supply (HVPS) power stage. When calculating "C" Series Trise, the output charge current available is 100% of rated lout. "C" Series units have ½ to 1/10 of the filter capacitance of "A" Series units, allowing more energy to go to the load capacitance. When using a "C" Series unit in a DC-bias application, an external capacitor is recommended for filtering.
