5kW DC-DC converter for fuel cells
Delta Electronics has developed a 5kW DC-DC power conversion and charging unit for use with hydrogen Fuel cells in industrial applications.
The unit uses a 6-phase boost topology design, which helps to protect the integrity of power equipment by preventing abrupt current spikes that hydrogen fuel cells may produce. The wide input voltage from 36 to 75V broadens its potential to support several applications powered by hydrogen fuel cells. The unit can also converts 43.2 ~ 57.6 V output voltage for the Li-ion batteries of electrical equipment.
The multi-phase interleaved boost design inside the unit features 6 phase diagrams to shunt sudden rise currents from hydrogen fuel cells. A Power limit feature alters the power supply speed in accordance with the energy-generating capability of various hydrogen fuel cells. The unit also features up to 93% efficiency, which is key to help reduce carbon footprint.
The RS-485 Modbus protocol and in-built digital signal processor (DSP) allow users to have real-time bi-directional communication with the unit and send the required signals.
“As hydrogen power is gradually becoming a major game-changer technology for mankind’s energy transition, our team applied Delta’s expertise in high-efficiency power electronics to develop this new 5kW DC-DC power conversion and charging unit as an integrated solution to enhance the power-generating process of hydrogen fuel cells,” said Hiroshi Chiu, General Manager of Delta’s Personal Computer Business Unit. “With its interleaved multi-phase boost design and wide input voltage, the unit is especially suitable for several applications that are increasingly adopting hydrogen fuel cells.”
