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  
metallized polypropylene, which features the controlled self-  
healing process, specially treated to have a very high dielectric  
strength in operating conditions up to 115°C.  
One unique feature of the segmented metallized technology  
is how the capacitor acts at the end of its lifetime. Unlike  
electrolytic capacitors, which are a short circuit failure mode,  
film capacitors only experience a parametric loss of capaci-  
tance with no catastrophic failure mode. The capacitor  
gradually loses capacitance over its lifetime and eventually  
becomes an open circuit.  
For more information on how segmented metallized films and  
controlled self-healing works see a complete presentation.  
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  
needs  
VEHICLES  
The FHC series capacitors are specifically designed to prevent  
ripple currents from reaching back to the power source, and to  
smooth out DC bus voltage variations. Capacitors are also used  
to protect semiconductors - originally thyristors, but now IGBTs.  
• Average applied voltage (expressed as a ratio vs nominal  
rated voltage)  
• Average hot spot temperature  
By changing any of these parameters we can change the  
defined “lifetime” of the capacitor. The capacitor will contin-  
ue to function even beyond the pre-established limit for  
capacitance decrease.  
STANDARDS  
IEC 61071-1, IEC 61071-2: Power electronic capacitors  
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.
