Development of Heat-robust DC-DC Converters for Hybrid EVs

A vehicle's power supply must function properly, regardless of whether the temperature in the surrounding environment is freezing cold or sweltering hot. However, ordinary ferrite does not work in certain temperature conditions.

Development of Heat-robust DC-DC Converters for Hybrid EVs

For this reason, as a pioneer of ferrite, TDK has sought to develop a special type of material that can cope with a wider temperature range. Employing ferrite, transformer, and heat simulation technologies to create a heat sink design, along with other properties, TDK has produced small, lightweight, high-efficiency DC-DC converters for hybrid electric vehicles that now lead the industry.

Small Light High efficiency
Today, TDK

Today, TDK's DC-DC converters are used in hybrid electric vehicles both in Japan and internationally,
helping to reduce power consumption during operation.
