DC-DC Converter for HV

Role of Converter

 The DC/DC converter we use for HVs is a down converter that converts voltage from the high-voltage batteries installed to run motors (rated 144 V, 288 V, etc.) to low-voltage batteries (12 V type), recharging the batteries and supplying power to electric components such as lights, audio, and ECUs.

Use and Compatibility

 With the electrification of vehicles comes the need for greater power supplies. Our power circuit technology, cultivated over many years, contributes to the protection of the environment through products with low energy loss.
As shown in the table below, we handle products for a broad range of systems according to application.

Product Introduction
Car DC-DC Converter
 The space in which to put car power is limited, requiring miniaturization and light weight. At the same time, the advancing use of electronics has brought diversification in electric parts and increased the current to be supplied. To solve the problem of this technical contradiction, we offer the ideal solution, not merely dealing with the power circuit or heat release technology, but strictly controlling internal temperatures with DSPs (Digital Signal Processors) and attaining harmonization with the whole automobile.
Technical points
Point 1
 For this power supply's main circuit structure, we have adopted a partial resonance full bridge system in order to enable zero-voltage switching with fewer parts, thus reducing the interior elements' switching loss. In particular, our setting of the normal actual-use load range to the peak of efficiency contributes to the further-yet heightening of vehicle fuel efficiency.
Point 2
 This power supply, by fully digitalizing the control circuit (DSP control), offers function and external communication such as was impossible with traditional analog control, along with high-precision power monitoring and high-speed control.
