A high-flexibility DC load for fuel cell and solar arrays power sources based on DC–DC converters

Step by step development of a real fuel cell system. Design, implementation, control and monitoring

“…3 shows the whole system made up by the fuel cell system, the monitoring system and the programmable electronic load Amrel PLA5K-120-1200 [25] used for experimental results. In comparison with other kind of DC loads used for testing renewable energy sources [26], a programmable electronic load is easy, it doesn't add ripple into the current provided by the source and it also supports the Constant Voltage (CV), Constant Current (CC), Constant Resistance (CR), and Constant Power (CP) modes of operation. Additionally with the monitoring system help user can get information about fuel cell system state operation, sensors measurements and actuators order or alarms situations.…”

Intelligent operations of distribution system with distributed generators

“…The PV is connected with DC-DC converter to apply the MPPT control. This system adopts the SEPIC (Single-Ended Primary Inductance Converter) as the buck-boost converter [10].…”

Design of closed-loop control system for a bidirectional full bridge DC/DC converter

“…With the development of electric energy storage technology, the application of bidirectional DC/ DC converter is being more and more widely [3]. Bidirectional DC/ DC converter is developed with the development of solar power, wind power generation, fuel cells and other new energy sources and storage device such as super capacitors and chemical power sources as representatives [4,5]. And with the further development of these kinds of pollution free power, Bidirectional DC/DC converter has been more and more widely used.…”
