In the era of rapid development of power technology today, high - power DCDC and bi - directional DCDC, as key equipment in the power conversion field, are disrupting the pattern of traditional power equipment with their excellent performance and innovative technologies.
High - power DCDC converters have extremely high power conversion efficiency and can achieve efficient and stable DC power conversion between different voltage levels. It is widely used in fields such as new energy vehicles, industrial automation, and power systems. In new energy vehicles, high - power DCDC converts the high - voltage DC power of the power battery into stable DC power required by the low - voltage electrical appliances in the vehicle, ensuring the normal operation of various vehicle systems, improving energy utilization efficiency, and extending the vehicle's cruising range.
Bi - directional DCDC is more flexible. It can not only achieve forward power conversion but also reverse conversion when needed. In energy storage systems, when the battery is charging, bi - directional DCDC efficiently stores the electrical energy from the power grid into the battery; when the battery is discharging, it can stably transmit the electrical energy of the battery to the power grid or load. This two - way flow characteristic greatly improves energy utilization efficiency and system flexibility, providing strong support for smart grids, distributed energy systems, etc.
