High-Power Bidirectional DC/DC: Multi-Scenario Applications, Multi-Functionality, Customizable - Shanghai Wenlida Power Electronics Co., Ltd.

Multi-scenario Applications

• New Energy Energy Storage: In integrated solar-storage-charging projects, it enables efficient voltage conversion when photovoltaic power is stored in batteries, and stable inversion when batteries discharge to loads or the power grid. In high-voltage platform energy storage applications, it can adapt to high-voltage battery systems, ensuring the stability and safety of energy storage equipment during charging and discharging.
• Power Protection: It is used for power support, ensuring the voltage stability of the power grid during different periods such as peak and valley load times, and improving power quality. In DC UPS systems, as a core component, it can quickly convert battery DC power into the voltage required by equipment when the mains power is interrupted, realizing uninterrupted power supply and ensuring the continuous and stable operation of key equipment such as data center servers and medical devices.
• Rail Transit: When electric locomotives such as subways and high-speed trains are running, the converter can recover a large amount of regenerative energy generated during braking, convert it into appropriate voltage for storage or feedback to the power grid. This not only saves energy but also reduces problems such as heat generation from braking resistors, lowering operating costs and equipment losses.
• New Energy Vehicles: It can be customized according to the battery voltage of different vehicle models, realizing efficient and stable power conversion between the battery and the vehicle's electrical system, ensuring the safety and stability of power transmission during charging and discharging.

Multiple Functions

• Automatic Switching between MPPT and Constant Voltage: In distributed power generation systems, it can real-time monitor the output power of photovoltaic panels and adjust its own working parameters to keep the photovoltaic panels working near the maximum power output point, thereby improving the efficiency of photovoltaic power generation. When the demand of the power generation system changes or the battery state reaches certain conditions, it can automatically switch to constant voltage mode to provide a stable voltage output for loads or batteries.
• Automatic Judgment of Charging Modes: Through built-in intelligent algorithms and sensors, it can automatically judge the type of battery, remaining power, and current charging state, thereby selecting the most appropriate charging mode, improving charging safety and efficiency, and extending battery life.
• Efficient Bidirectional Power Conversion: Adopting advanced topological structures and control strategies, during forward conversion, it can convert high-voltage DC power into low voltage to supply power to loads; during reverse conversion, it can feed back the power generated by loads or battery discharge to the high-voltage DC power system. The bidirectional conversion efficiency can reach more than 98%.

Customizability

• Power Customization: From low-power precision instrument power supply to high-power demand of large industrial equipment, Wenlida can select suitable power switching devices, inductors, capacitors and other components according to customers' actual power requirements, and optimize the circuit layout and heat dissipation design to ensure that the converter can work stably and efficiently at different power levels.
• Interface and Communication Customization: Various types and quantities of interfaces can be customized to facilitate seamless connection and communication with other equipment. In smart grid construction, it can be integrated with grid monitoring systems and communication networks to realize remote monitoring and intelligent scheduling; in industrial automation production lines, it can communicate smoothly with PLC and other control equipment to precisely regulate power output according to production processes.
• Protection and Heat Dissipation Customization: For special working environments such as high temperature, high humidity, and dust, Wenlida will customize protection and heat dissipation solutions. For example, in high-temperature environments, high-efficiency heat dissipation fins, forced air cooling or water cooling systems are adopted; in high-humidity environments, moisture-proof and anti-corrosion materials and special protective coatings are selected to improve equipment reliability and service life.
• Voltage Level Customization: Covering various voltage levels such as 60V, 800V, 1200V, 1500V, 2000V, and 2400V, it can be widely adapted to different application scenarios.
