PROBLEM TO BE SOLVED: To charge respective capacitors uniformly, which comprise a voltage multistage converter. SOLUTION: This electronic device is provided with a control means which involves means (VMO, VM12,..., VMOn) for evaluating average voltage at the terminals of respective capacitors (C1r C2,..., Cn), means (VE1, VE2,..., VEn) for confirming a difference between evaluated average charging voltage and the nominal average charging voltage of the capacitors, if any, and compensation control means (MCC1, MCC2,..., MCCn) for changing the timing position of a control signal from this converter in such a direction the confirming difference decreases. |
