摘要： PROBLEM TO BE SOLVED: To reduce a heat loss due to initialization of a capacitor by a method wherein a reference voltage is set at a voltage at several fractions of a fully charged voltage and initialization of a charging operation is corrected. SOLUTION: Respective capacitors are discharged completely. The designated signal SHn of a maximum capacitor, e.g. Cn, is set at 'H', and flip-flop 12i and a flip-flop 13i are reset. Thereby, selection signals S11,... Sn1 of a changeover switch at a parallel monitor are set at 'L', and selection signals S12,... Sn2 are set at 'H'. As a result, a reference voltage at a low voltage used to correct initialization of a charging operation is connected to respective comparison terminals. When the charging operation is started, the charging voltage of the respective capacitors is raised so as to reach the reference voltage sequentially. The output of a comparator CMP1 is set at 'H', the selection signals S11,... Sn1 are set at 'H', and the selection signals S12,... Sn2 are inverted to 'L'. Consequently, a finish signal SB which corrects the initialization as the output of an OR gate 17 is set at 'H', all the flip-flops are reset, the output is returned to 'H', and the correction of the initialization of the charging operation is finished.
