Automatic voltage/current profile calculation from reference parameters Autosequencing through power profiles, at user-defined intervals Graphical view of profile and real-time power supply output Flexible profile generation for manual or automatic operation Up to 50 voltage and current points per curve, with piecewise linear approximation performed between points and higher point density around maximum power point Compatible with Magna-Power Electronics dc power supplies
The Photovoltaic Power Profile Emulation (PPPE) software automatically calculates solar array voltage and current profiles based on user-defined parameters. These profiles can be sequentially sent to a Magna-Power Electronics' power supply, which will emulate defined characteristics. The user can define a limitless number of profiles to be emulated and sequenced over a given time period.
Design and production validation for photovoltaic connected electronics requires a photovoltaic emulating power source with flexible output characteristics. Inverters and specialized dc-dc converters employ maximum power point tracking (MPPT) control algorithms to maximize utilization of nonlinear energy sources, such as solar panels and wind turbines. For development and manufacturing, using photovoltaic arrays for validation is costly with uncontrolled source characteristics. By utilizing a power supply with user-programmable output characteristics, the user can evaluate the full range of power conditions.
