Customer ServiceTo ensure safety, batteries need to be disconnected from any charge or load in case of malfunction. This is the task of the battery disconnect unit (BDU), which is part of the BMS. The BDU contains a fuse and DC high-voltage contactors. In case of a failure, the BMS sends a command to the high-voltage contactor to disconnect the battery.
Extending the battery run-time becomes the top priority for the system designers. This paper overviews five commonly used DC-DC conversion topologies suitable for battery operated systems: Buck, Boost, non-inverting Buck-Boost, Charge Pump and Flyback converters.
Basics of DC switching Whenever an electrical high-power device is turned off und load (for example, motors, transformers, energy storage or similar power loads), its switch, relay or contactor transitions from a closed to an open state under load and an electrical arc (break arc) occurs between the two contact points (electrodes) of the switch.
Among them, the switching DC-DC converters are more efficient than LDO and charge pump converters, but more expensive and complicated. Designing a high efficiency DC-DC converter for these portable devices is challenging due to the special requirements of a battery operated system, such as a wide input voltage variation and dynamic operating load.
By offering a flexible and adaptable solution that integrates both DC-DC and DC-AC conversion capabilities, the proposed converter simplifies system architecture, reduces costs, and enhances reliability. It also provides significant benefits for domestic consumers and facilitates the integration of renewable energy sources.
Zheng et al. 23 developed a high-voltage DC-DC converter that adapts its switching frequency based on the load conditions, improving the overall efficiency of the converter. This technique is particularly beneficial for applications requiring high-voltage conversion with minimal losses.
