This article describes a high-voltage power supply using piezoelectric ceramic transformer power supply, the power supply output voltage of 2000 volts. The use of series voltage regulator system, and to take the ceramic transformer operating frequency tracking resonant frequency and temperature compensation and other measures to make the stability of the power supply has greatly improved, the main features of the power supply: in a wide temperature range, with more High stability, relative drift of output voltage <0.3% in the range of -50 ℃ ~ + 65 ℃, relative change of output voltage <0.3% when the input voltage of the power supply changes ± 10%; The power supply has negative resistance Features, no-load output voltage lower than the on-load output voltage; small size, light weight, weight <1Kg.
