A new topology of fuel cell hybrid power source for efficient operation and high reliability

▶ It is proposed a MPP tracking control that tracks to within 1% the Maximum Power Point (MPP) of PEM Fuel Cell (PEMFC) stack. ▶ The MPP tracking solution is used in proposed FC Hybrid Power Source (HPS) topology for purposes of both integrity and efficiency of it. ▶ The use of a HPS (of FC, ultracapacitors and batteries) permits reduction of the hydrogen consumption and a reliable FC HPS operating under sharp power pulses. ▶ Also, the proposed FC HPS structure has a nonlinear control loop for ripple mitigation of inverter current. ▶ The obtained ripple factor is up to 1%.
