Power Conditioner System
fuji electric provides central type and string type solarinverters.
Adoption of new IGBT and new circuit system
Fuji Electric commercialized the world’s first three-level module in which a new RB-IGBT * and an existing IGBT are integrated in one package.
Application of this new module to a new three-level conversion circuit enables a large reduction both in power loss and in the number of parts, resulting in high efficiency and low noise in the equipment.

Highest efficiency 98.5%(DC 1,000 V product)
Compared to existing products, our new power conversion technology, which uses a new three-level conversion circuit in the new module, reduces switching loss in the IGBT device and also reduces filter loss by reducing to one half the harmonics in PWM waveform from the inverter. This results in the world highest efficiency of 98.8% (DC 1,000 V product).

Fuji Electric provides a substation type of PCS that can be installed outdoors.
A switchgear, a step-up transformer, and PCS can be provided together.
Optional fuses for a DC branch in the PCS can be equipped.
Standard FRT function
The fault ride through (FRT) function that is becoming essential in PCS for large-scale photovoltaic power generation is provided as a standard function.
