Abstract
A method of determining a high voltage value without measuring the high voltage value directly, in varying possible temperatures. An apparatus includes two voltage divider circuits (), wherein the second circuit (i.e. a reference circuit) is provided with a smaller reference input voltage (). The transfer ratio can be obtained from the reference circuit () through voltage measurements, and deduced into a transfer ratio of another circuit (), no matter the ambient temperature value. When measuring a divided voltage value () of one circuit (), the desired high voltage value () can be calculated, no matter what the ambient temperature is.
