Fuel Cell DC/DC Converter

As a key component of the hydrogen fuel cell engine system, DC/DC converter is used to boost the low-voltage DC output from the fuel cell into high-voltage DC output, providing electric energy to the EV and charging power battery at the same time.

Through the accurate control of the hydrogen fuel cell engine output power, DC/DC converter can fulfill the power distribution and optimal control in the vehicle power systems.
