Power semiconductors and ICs for power supply for "heat pump water heaters".

Power semiconductors and ICs for power supply for "heat pump water heaters".

The high-reliability power supply manufacturer "Shin Denko" develops power semiconductors for rapid design of auxiliary power supplies for heat pump water heaters and inverters for motor drives!

Heat pump water heaters can be compacted and simplified by using a dedicated power IC to configure the flyback circuit for auxiliary power supply, reducing the number of components. Since it is an isolated power supply, we recommend low-loss diodes for the secondary rectification circuit. For motor drive applications, we can propose a set of gate diodes and a 600V high-voltage driver IC. The "heat pump water heater," which is expected to have high energy conversion efficiency and utilize renewable energy, is a perfect match for resource-saving and low-loss power circuits! Shin-Dengen Power Semiconductors has a wealth of experience in home appliances! ■ Develop new products with the latest power circuits! When the power circuit is perfectly designed, it results in a pleasant new product. At Shin-Dengen Industries, we offer a wide range of power semiconductors suitable for various applications, from bridge diodes to power MOSFETs and power ICs, enabling you to quickly build high-quality power circuits. For energy-saving and space-saving solutions, consult the power experts at Shin-Dengen Industries.
