Hybrid Vehicles and Electric Vehicles Capacitors General Description The FHC1 & FHC2 range capacitor have been specially design to be use in conjunction with Hybrid & Electric vehicles IGBT modules. DC FILTERING LIFETIME EXPECTANCY The series uses a dry-wound (non-oil-filled) segmented One unique feature of the segmented metallized technology metallized polypropylene, which features the controlled self- is how the capacitor acts at the end of its lifetime. Unlike healing process, specially treated to have a very high dielectric electrolytic capacitors, which are a short circuit failure mode, strength in operating conditions up to 115C. film capacitors only experience a parametric loss of capaci- tance with no catastrophic failure mode. The capacitor For more information on how segmented metallized films and gradually loses capacitance over its lifetime and eventually controlled self-healing works see a complete presentation. becomes an open circuit. Lifetime, therefore, as it is defined here, is a function of several elements: APPLICATIONS IN ELECTRIC Decrease in capacitance limit 2-5% or to meet customer VEHICLES needs The FHC series capacitors are specifically designed to prevent ripple currents from reaching back to the power source, and to Average applied voltage (expressed as a ratio vs nominal smooth out DC bus voltage variations. Capacitors are also used rated voltage) to protect semiconductors - originally thyristors, but now IGBTs. Average hot spot temperature By changing any of these parameters we can change the defined lifetime of the capacitor. The capacitor will contin- STANDARDS ue to function even beyond the pre-established limit for IEC 61071-1, IEC 61071-2: Power electronic capacitors capacitance decrease. AECQ 200: with specific deviation for power capacitors CONSTRUCTION The internal construction of the FHC Series is based on several elementary wound bobbins soldered by reinforced solder point on specific bus bar offering, the benefits of which include: flexibility in internal design, current capability and repartition, reduction of thermal expansion constraints, high winding productivity, modularity in three dimensions. PACKAGING FHC Series capacitors are enclosed in an unpainted, rectangu- lar, resin filled plastic case. Aluminium cases are available upon request. 030717 1 HEV/EV CapsHEV/EV Caps Hybrid Vehicles and Electric Vehicles Capacitors FHC1 & FHC2 HOW TO ORDER FHC 1 6 I 2637 Series Case Size Dielectric Voltage Capacitance -- = front facing mounting brackets FHC: HEV/EV DC-Link 1 = 170mmx50mm 6 = PP (polypropylene) I = 410/450 Vdc EIA Code JH = side facing mounting brackets single terminal J = 700 Vdc 2= 237mm x 72mm C = 900 Vdc three terminal CHARACTERISTICS Voltage: 410VDC to 900Vdc (standard) 300VDC to 1400Vdc (custom) Capacitance Value: 300F - 900F (standard) 100F - 1.5mF (custom) Working Temperature: -40C to 105C hot spot temperature up to 115C hot spot for low duration ELECTRICAL CHARACTERISTICS Capacitance tolerance 10% -4 Tan 2 x 10 0 Test voltage between terminals (10s) 1.5 x Un 25C Test voltage between terminals and case (60s 50Hz) 3 kVrms 25C Hot spot max *** 105C / 115C low duration Temp Min -40C Temp Max +105C Storage +105C / -40C Lifetime: DC/C = -5% Up to 15 000h *** Thermal calculation**** (Q in VAR, Rs in Ohms, -4 Rth in C/W,T ambient without cooling plate ) T Hot-spot = Tambiant + (2*10 .
