DC/DC Converters

As automotive electronics continue to make advances, there is an increasing demand for powering electronic components. Now vehicle mounting designs, for example, also require inverters, motors and high-voltage batteries, and they have become more high-density with each generation. As a result, the power capacity must be increased for DC/DC converters, and they must be downsized further and made more lightweight. To address these expectations, Shindengen offers low-loss from soft switching circuits, as well as high heat dissipation and thermal dissipation technology. In addition, full digital control with a DSP (digital signal processor) helps optimize power control, strengthen safety designs and enable communication with the controlling ECU. The DC/DC converter has the advantage of being able to combine specific circuits and components to support various vehicle cooling methods using one of the following three types: forced air cooling type, non-waterproof and waterproof water cooling types.
