System modeling and simulation

Our system is designed for product to have the optimized conversion efficiency through individual parts and whole system analysis by developing simulation model for the optimized system operating feature of power conversion. The system can predict the potential problems during development in the early period for solution because the effective verification of signal handling algorithm, which is realized by DSP, is possible through the simulation of power circuit.

Design of board circuit and verification

It can shorten the development cycle, and reduce the trials and errors during board manufacturing because the design of control and power stack board, spice simulation and board design are conducted in the same integrated environment by using Altium Designer software, which is the newest 3D EDA tool.

Product reliability secured

We provide customers with the best quality and function through power gauge test and field test which comply with the international test standard (PV Simulator & Grid Simulator owned)
