Power optimizer solutions
DC-DC power optimizers convert variable DC voltage from photovoltaic (PV) panels to a fixed DC voltage.
This is also referred to as the maximum power point tracking (MPPT) stage. MPPT is a technique used to maximize power extraction under any environmental conditions, including changes in irradiation levels and temperature. MPPT can happen either be conducted directly at and separately for a PV panel through single units installed at each panel or at a preliminary buck/boost stage of an inverter where several photovoltaic panels are connected in series at the input.
Installing a power optimizer on a PV panel also enables a rapid shutdown function (RSF) to be implemented, which is required for residential solar installations in some regions. Stand-alone power optimizers operate outdoors under harsh conditions and so a compact form factor, high-efficiency levels and a long lifetime are crucial success factors for these units.
We offer a wide range of products with different packages and technologies, including silicon (Si), silicon carbide (SiC) and gallium nitride (GaN). This enables manufacturers to create optimized, efficient solutions for single-panel and multi-panel micro inverter designs.
We offer the following products for stand-alone power optimizers:
- Panel level
< 500 W: For the modular approach were each PV panel is equipped with a Power Optimizer a solution with Infineon’s OptiMOS™ MOSFET and 2EDL EiceDRIVER provides the highest performance and lowest form factor.
- String level
1-20 kW: Infineon discrete solution such as our Silicon CoolMOS™ and Silicon Carbide CoolSiC™ MOSFETs, HighSpeed3 IGBTs and TRENCHSTOP™ IGBT6 technology, that enables designers to maximize price/performance ratio,.
- > 20 kW: Our Easy CoolSiC™ module enables designers to increase the efficiency and lower the weight of the booster stage
