Description
Technical Field
The invention belongs to the field of photovoltaic cell testing, and particularly relates to a xenon lamp triggering device and a control method.
Background
With the continuous development of photovoltaic power generation technology, the photovoltaic cell manufacturing technology is continuously improved, and the requirements for testing the power generation performance and efficiency of the cell are higher and higher. Photovoltaic cells are typically tested in the laboratory by steady state solar simulators that simulate standard sunlight by light from xenon lamps.
The xenon lamp is lighted and needs ten thousand volts of high voltages to trigger, and the high voltage trigger circuit of most xenon lamps at present generally adopts an internal trigger type xenon lamp circuit, and the basic working principle is as follows: when the circuit is started, the alternating voltage starts to supply power to the circuit, and direct current is output after the processing of rectification, filtering, voltage stabilization and the like in the switching power supply. The capacitor, the metal coil of the trigger and the xenon lamp form a closed LC oscillating circuit, so that the xenon lamp is triggered. After the xenon lamp is triggered, the capacitor in the LC circuit is discharged, the trigger does not work any more, and the xenon lamp works stably by the constant-voltage direct current output by the switching power supply. However, this triggering method has not been successful in igniting high power xenon lamps. Through research and analysis on a full volt-ampere characteristic diagram of discharge of a gas xenon lamp, the fact that voltages required at two ends of the xenon lamp are particularly high in an avalanche discharge process of a volt-ampere characteristic curve is found, and if the trigger voltage is not high enough, the xenon cannot be ionized, and the trigger fails. On the other hand, the working current of the xenon lamp is higher and can reach 50A. Therefore, the xenon lamp driving power supply can output both higher voltage and higher current, which has higher requirement on the index of the xenon lamp power supply.
Therefore, the xenon lamp is triggered in a combined mode of the driving power supply and the triggering power supply, so that the problem of success rate of triggering the high-power xenon lamp is solved, and meanwhile, the power supply cost is reduced.
