Power Film Capacitors for Next Generation Inverter Designs

DC Link capacitors provide bulk energy storage and ripple filtering for inverter applications. Many inverters are designed with excess aluminum electrolytic capacitors across the bus in order to handle the ripple current. Type 947C Power Film capacitors have higher voltage and current ratings allowing them to replace complex series-parallel combinations of aluminum capacitors. The 947C series capacitors are ideally suited as DC Link capacitors for wind, solar and fuel cell inverters.

Type 947C Power Film Capacitors offer advantages over Aluminum Electrolytic Capacitors:

• Voltages exceeding 1200 Vdc eliminates the need for complex series/parallel connections.
• 1/3 the cost per amp of ripple.
• Dry construction, no electrolyte.
