2kW＆1kW Output Power Isolated Step-Down DC/DC Converter for Automotive Applications
Outline
Since its founding in 1949, Shindengen Electric Manufacturing Co., Ltd. has been cultivating power supply technology. With the evolution of car electronics, the required vehicle load is increasing, while power supplies are required to be more compact and lightweight. To meet these demands, our company adopts low-loss soft switching circuits and high heat dissipation and thermal dispersion technologies. Additionally, by using DSP for full digital control, optimal power supply control and safety design are possible, and communication with higher-level ECUs is also realized.
This is an isolated DC/DC converter that converts the highvoltage DC battery of an electric vehicle into low-voltage DC and supplies power to the 12V power line for auxiliary equipment.

Use・Results
～Introduction of Use Cases～
【High Current System Example】-Parallel-Operation-
With the increase in auxiliary power due to the evolution of car electronics and theevolution of autonomous driving technology, DC/DC converters with higher output are also required. By using DC/DC converters capable of parallel operation, we respond tothe growing demand for auxiliary power systems.
・This is an example of a system in which a sub DC/DC converter is added in parallel as abooster when a high-current converter is needed.
・Distributing the auxiliary power helps prevent the wire harness and main fuse frombecoming larger, which can occur due to increased current from the DC/DC converter.
■Output characteristics during parallel operation
This is the output current and voltage characteristic when 2kW and 1kW are combined and operated in parallel. It is possible to correct the output current value of the two converters so that they can be supplied in a balanced manner. Even if a vehicle load is added and the required current increases, if there is a DC/DC that can operate in parallel, it is possible to easily supply power from the sub DC/DC converter.
【Redundant System Example】 -Redundant Operation-
When configuring a fully redundant autonomous driving system, it is necessary to also make the auxiliary power supply redundant. By using DC/DC converters, we can meet the needs of various auxiliary power supply systems.
・Autonomous Driving
Sub DC/DC Converter can be set to secure the redundancy of the autonomous driving system.
・Dual Battery System
Dedicated DC/DC Converter can be set for a 12V battery as a sub power supply in a 24V system.
