Chroma has developed two software modules that integrate a DC power supply and an electronic load for battery pack testing. The Battery Charge/Discharge Testing Software programs the test sequence, loop and stop conditions. The measured voltage, current and power data is recorded in a file for future analysis. The Dynamic Current Waveform Simulation Software records to an Excel compatible file actual discharge current waveforms from...

A PV system is an energy system which directly converts energy from the sunlight into electricity. Once light hits the solar cell (array), electricity is generated and the DC is collected at a PV inverter. PV inverter is a device that changes DC power to AC power and is also a key component in PV systems. There are two main types of PV systems, Grid...
