摘要： A power source device includes an oscillator generating a clock, a frequency division unit dividing the clock to output a pulse, a sequence generation unit generating sequences “N” with respect to each switching of the pulse, a frequency division ratio setting unit setting frequency division ratio, a switching element driven by the pulse, and a piezoelectric transformer outputting alternating high voltage from a secondary-side when a primary-side is applied with voltage. The generated sequence and the set frequency division ratio are compared to output the pulses of fractional-M, −M+1 frequencies. An average frequency division ratio of the pulses of fractional-M, −M+1 frequencies determined by (M×α)+(M+1)×β/(α+β), where α and β respectively represent the number of pulses of “M” and “M+1” per unit time. The average frequency division ratio and frequency division ratio become equal at a sequence generation cycle and approximated in a period shorter than the sequence generation cycle.

摘要： A power supply device includes: an oscillator configured to output a clock signal; a pulse output unit configured to output a pulse by dividing the frequency of the clock signal; a switching element driven by the pulse; a piezoelectric transformer configured to intermittently receive a voltage from the switching element and to output a high alternating current voltage; a rectifier configured to convert the high alternating current voltage to a high direct current voltage; an output voltage conversion unit configured to convert the high direct current voltage to a low direct current voltage; a target setter configured to output a target value; and a comparison unit configured to compare the low direct current voltage with the target value and to output a comparison result. A frequency division ratio of the pulse is controlled according to the comparison result, and thereby is changed so as to obtain the target value.
