Description

technical field [0001] The invention relates to an integrated positive and negative continuous linear adjustable high voltage output power supply circuit applied in the fields of industry, scientific research, biomedicine and the like. Background technique [0002] In the field of industry and scientific research, some testing instruments need to work under positive and negative high voltages. There are many types of high-voltage power supplies that can independently output positive and negative high voltages on the market, but there are few integrated positive and negative continuously adjustable high-voltage power supplies. Automatic remote control is the trend of industrial and technological development, which also puts forward higher requirements for the linearity between the output voltage of the high-voltage power supply and the input voltage of the control terminal. Low linearity will lead to deviations in subsequent data statistics and result analysis, affecting test...
