The modern energy storage system of lithium-ion batteries has been widely adopted in various applications due to its efficient and reliable performance. However, ensuring the safety and stability of the system requires strict monitoring of each battery unit to prevent battery imbalance, overcharging, deep discharge, or overheating. To achieve this goal, it is necessary to provide independent isolated power supply voltage control circuits for each battery unit or battery array.
For battery arrays with a nominal voltage of up to 48V, standard industrial DC/DC power converter modules that provide 500V or 1600V isolation barriers can usually be used. However, for systems that require higher power and are connected to AC power sources, the battery array voltage may reach 600-800V, which requires solutions with higher isolation barriers.
Low isolation capacitance enhances noise resistance
The P-DUKE medical power converter series has a 5kV isolation barrier, exceeding the conventional requirement of 4kV. In this project, MPD30-24S12 was selected, which can generate the necessary 12V/30W power voltage from the common 24V DC bus.
The input and output capacitance of a typical industrial 30W DC/DC power converter can reach 1500pF. If up to 200 converters are used in parallel, the total capacitance between the battery unit (connected to the AC grid through a charger) and the 24V bus may reach 300nF, resulting in an AC leakage current exceeding 20mA. A current exceeding 10mA may cause serious electric shock and accidents.
The input and output capacitance of MPD30-24S12 is only 20pF, so the total capacitance after 200 converters are connected in parallel is only 4nF, and the leakage current is less than 1mA. This low capacitance also avoids transient or any noise coupling from the AC/battery side converter to the sensitive communication signal of the central battery management system.
Through this solution, the requirements for 4kV isolation and low leakage current have been well met.
Communication and Power Solutions
For communication throughout the installation, the central BMS controller uses a WiFi router and is powered by a 25W 53V power supply via Ethernet. According to the final installation, the power supply voltage can be generated by a 230Vac main power supply or an internal 24Vdc bus. For 230Vac, TSD30 series converters can be used. It also offers a Din rail version for easy installation in the controller rack.
Successful cases have shown that the RCD30 series converter can generate a 53V voltage from the 24Vdc bus and adjust the output from 54V to 53V. It also comes with an integrated heat sink for easy cooling.
P-DUKE product application
The MPD30/MPD30W series is a series of 30W DC/DC power converters with enhanced 5000Vac isolation voltage, which meets the requirements of medical applications. This series has different input voltage ranges and provides single or dual output. This series complies with the 2MOPP standard, with an electrical clearance and creepage distance of 8 millimeters. This makes them suitable not only for medical devices, but also for other applications that require high isolation and extremely low input/output capacitance.
The TSD30 series is a ready to use AC/DC solution suitable for Din rail applications. Like the RCD30W series, it provides different output voltages and installation options for various applications.
