Power semiconductors are the silent heroes of the power grid, enabling the efficient, reliable, and resilient flow of electricity that modern societies depend on. Hidden inside converters, substations, and control systems, they regulate voltage, current, and power quality while minimizing losses. As renewable generation, electrification, and digitalization accelerate, advanced power semiconductor technologies become essential for grid stability, efficiency, and sustainability. Their continuous innovation underpins the transition toward smarter, greener, and more robust power grids worldwide. We are Hitachi Energy Semiconductors and offer an extensive portfolio of highly reliable medium- and high-voltage power semiconductors for the most demanding applications.
