THPSC029	300 kV High-Voltage Source With Up to 15 kW Output Power	606
	D.V. Senkov, I.A. Gusev, A.Yu. Protopopov, D.N. Pureskin, M.A. Scheglov BINP SB RAS, Novosibirsk, Russia
	The presented report contains the description of high-voltage source with output voltage up to 300 kV and output current up to 50 mA. The source consist of the chopper with IGBT switches working with a principle of pulse-width modulation and the full H-bridge converter with IGBT switches, both working on programmed from 15 to 25 kHz frequency, and the high voltage transformer powering the eight-stage multiplier with the additional capacity filter at output. The transformer and multiplier both are made in common volume separated on oil tank part with silicon oil for transformer and SF6 part for multiplier. The additional capacity filter provides low ripple and noise level in working range of output currents. The source can operate in normal mode with series of high-voltage breakdown in output voltage. In the high-voltage breakdown the released in load and matching circuit energy is less than 40 J at maximum operating voltage 300kV. The efficiency of system is more than 80% at the nominally output power 15 kW. The description of the source and the test results are presented.

THPSC030	High-Precision Ramped High-Voltage Source With Up to 50 kV Output Voltage	609
	D.V. Senkov, A.M. Batrakov, I.A. Gusev, A.Yu. Protopopov, A.A. Zharikov BINP SB RAS, Novosibirsk, Russia
	This report describes the precision high-voltage ramped high-voltage power system. The output voltage up to 50 kV with 10 ppm precision. The power system consists of the 3 kW high-voltage source based on multiplier, presision high-voltage divider with digital interface and high-voltage discharge switch to provide low ramp-down time for output voltage. The power system is planed to use in the NIKA booster electron cooler project. The description and test results are presented.
