Mitsubishi Electric has incorporated a gradationally-controlled voltage inverter and other new technologies in its PV inverter, to minimize power loss and maximize power conversion efficiency.
Employing Mitsubishi Electric's unique gradationally-controlled voltage inverter technology, which outputs quasi-sinusoidal waves, and incorporating the newly-developed MOSFET¹ module for gradational control, this PV inverter reduces electric conversion loss by 44% compared to conventional models, and delivers the industry's highest power conversion efficiency of 97.5%².
Gradational quasi-sinusoidal waves are directly output by combining three different-voltage inverters.
We have developed a new MOSFET module that incorporates all MOSFETs constituting a gradationally-controlled voltage inverter.
The output of quasi-sinusoidal waves by the inverter reduces loads on the filter and semiconductor devices. Power loss is also reduced by 44%.
Reduced power loss has minimized heat generation, making it possible to simplify the air path and create an enclosed structure for greater moisture resistance. Thanks to this structure, the unit can now be installed in shower rooms and bathrooms, where it previously could not be.
