EPCOS Product Brief 2017 Film Capacitors For Solar Inverters in Photovoltaic Systems Photovoltaic systems consist of multiple components, including cells, mechanical and electrical connections or mountings. They regulate and/or modify the electrical output. The generated electricity can be stored, used directly or fed into a large grid powered by central generating plants connected or tied to the grid. The solar inverter transforms DC to AC current. Power electronic designers are under increasing pressure to achieve: • Higher power requirements with very high efficiencies • Overvoltage and overcurrent protection due to switching failures, lightning, ground faults, safety regulations etc. • Long-term stability and reliability • Use of approved materials and components according to recognized institutes such as UL and VDE EPCOS offers specific products for many circuit functions, depending on the application requirements. Thus, its film capacitor technology is particularly suitable for power electronics designers looking for proven performance: • Higher rated voltages compared to other capacitor technologies • Option of AC operation (reverse current) • High overvoltage capability due to their self-healing properties • Lower equivalent serial resistance (ESR) and inductance (ESL) • Higher power operation (Irms vs. frequency) • Stability of electrical parameters over time and temperature

Film Capacitors Technical data Capacitance Ordering code/ type VRMS: 305 V AC VRMS: 350 V AC VRMS: 300 V AC Snubber capacitors Output filter capacitors Data sheets are available under www.epcos.com using the Search by ordering code function. Custom specific design upon request. Structure of ordering codes: The ordering code for one and the same product can be represented differently in data sheets, data books, other publications and the website of EPCOS, or in order-related documents such as shipping notes, order confirmations and product labels. The varying representations of the ordering codes...
