Abstract As the situation that the presently available DC load lacks power reversal capability and its power tracking performance is inadequate, a controllable DC load with regenerative feedback capability is proposed, in order to adequately research the control operations of the fuel cell hybrid power system energy management strategy during the various power conditions. For the controllable DC load, the main circuit topology composed of bidirectional Buck-Boost DC/DC converter and battery is adopted to accommodate bidirectional power flow; multi-loop control is proposed as the control method to effectively improve the power tracking performance. The simulation results of Matlab/Simulink show that the proposed controllable DC load with regenerative feedback capability can accommodate bidirectional power flow, and has high power tracking performance.
