Fuji’s semiconductors: On the forefront of innovation

Semiconductors play a crucial role in the production of electronic devices and are thus an important part of our daily lives. Over the past 50 years, advancements in semiconductor technology have helped making electronic devices smaller, faster, more reliable and efficient – just think about the smartphone.
Fuji Electric is proud to be at the forefront of these innovations, offering high-performance power semiconductors for energy, automotive and industrial applications. In addition to MOSFET devices and diodes, Fuji Electric’s environmentally friendly product range includes power semiconductor modules, which are an indispensable component in energy-saving power electronics, and control ICs, which are required in high-efficiency power supplies.

What are Power Semiconductors?

A semiconductor is a substance that conducts electricity easily while acting as an insulator to prevent the flow of electricity. The use of semiconductors enables the rectification of the current flow in one direction, the amplification of the electrical signals and the switching to open and close the current flow.

Power semiconductors can handle high voltages and large currents.

Failures can occur due to a rise in temperature caused by heat generation when operating large powers. Therefore, Fuji has been working on developing methods to reduce the loss of semiconductors and effectively dissipating the generated heat to the outside.

Power semiconductors are mainly used in power conversion, e. g. changing voltages and frequencies and converting direct current to alternating current (DC->AC) and vice versa. Power semiconductors play an indispensable role in precisely driving motors at low to high speeds, supplying power grids with electricity generated from solar cells with lower power losses, and providing a stable power source for various home appliances and electrical equipment.

In recent years, there has been a growing awareness of the need to save energy and reduce power consumption, and as a result, the need for power semiconductors that minimize power loss has increased.
