Newbase Releases 185V~850V Bidirectional EV DC-DC Converter with 3000W Output & IP67 Protection

Newbase Releases 185V~850V Bidirectional DC-DC Converter for Electric Vehicles

Zhengzhou Newbase Auto Electronics Co., Ltd. (Newbase) has expanded its new energy vehicle power electronics portfolio with the release of a high-voltage bidirectional DC-DC converter engineered for demanding electric vehicle platforms. The new unit accepts a wide 185V to 850V input range and delivers a stable 27.5V low-voltage output with up to 3000W of power, making it a strong fit for modern electric buses, trucks and commercial EVs.

As electric vehicles move toward higher-voltage battery packs, reliable and efficient DC-DC conversion has become critical to vehicle electrical architecture. Newbase's bidirectional design allows energy to flow in both directions, supporting both the charging of the low-voltage auxiliary battery and the supply of power back to the high-voltage bus. This flexibility helps vehicle makers simplify system design and improve overall energy efficiency.
