摘要： A high voltage capacitor is disclosed that comprises a grounding member (1), two through type capacitors (2 and 3), an insulating case (6) and insulating resin (71 and 72). The grounding member (1) has two raised portions (101 and 102) on which the through type capacitors (2 and 3) are secured. The insulating case (6) has two hollow cylindrical portions (61, 62) spaced apart by a distance D with their upper open ends joined to each other to form a recessed enclosure (63) in line with and following the inner diameter sections (611, 621) of the hollow cylindrical portions (61, 82) and their lower open ends fitted on the outer circumference of the raised portions (101, 102). The insulating resin (71 and 72) is provided around the through type capacitors (2 and 3) within the inner diameter sections (611, 621). It is thus possible to provide a high voltage capacitor with superior mechanical strength and excellent withstand voltage characteristics even in humid environments and that is small in size and inexpensive.

摘要： A general-purpose comparator can be used as a comparison processing module to reduce the costs of a motor drive control apparatus. The apparatus has an electric machine; a magnetic pole position computation processing module; a pattern generation processing module; a switching angle computation processing module which computes a switching angle where switching is done in a next control period based on a pulse pattern; a comparison processing module which compares the magnetic pole position with the computed switching angle to generate a comparison signal; and an on-off output processing module which generates a PWM signal based on the comparison signal indicative of the comparison result. In this case, because the magnetic pole position is compared with the computed switching angle to generate the PWM signal based on the comparison signal, a general-purpose comparator can be used as the comparison processing module.
