Abstract

The invention relates to a solar simulator charging and discharging device and method and a solar simulator. The device comprises a microcontroller, a relay switch circuit, a semiconductor switch circuit, an energy storage circuit, a constant light control circuit and a light source, and the microcontroller controls the relay switch circuit and the semiconductor switch circuit to be switched off and controls the energy storage circuit to discharge electricity to the light source through the constant light control circuit when receiving a flashing command signal, so that the light source flashes. According to the invention, rapid turn-off of the charging loop is achieved by turning off the semiconductor switch circuit; and the charging loop and the discharging loop are completely isolated by turning off the relay switch circuit, so that the influence of the charging loop on the constant-light control circuit in the discharging loop is blocked when a flash test is performed on the lightsource, and the control precision of the constant-light control circuit is improved.

Description

Technical field [0001] The invention relates to the field of solar simulators, in particular to a solar simulator charging and discharging device, method and solar simulator. Background technique [0002] The solar simulator is divided into a charging standby state and a flash test stage in the working state. In the charging standby stage, the solar simulator will charge the energy storage capacitor according to the voltage value set by itself, and disconnect the charging when the set voltage is reached. Enter the standby phase; when receiving the external flash signal, the solar simulator enters the flash test phase, the charging system will be disconnected, the energy storage capacitor discharges the light source through the constant light device, and the light source is lit; the solar simulator will Frequent switching between these two states, the existing simulators generally switching speeds are about one second. [0003] In addition, the charging power supply of the solar si...
