OVER VOLTAGE PROTECTION TESTING APPARATUS

摘要

An over voltage protection testing apparatus is applied for testing an over voltage protection function of a power supply apparatus. The over voltage protection testing apparatus mainly includes a voltage boost-storage unit and an energy release unit. The voltage boost-storage unit boosts an original output voltage outputted from the power supply apparatus into a testing voltage.;Therefore, no extra testing voltage source is required for testing the over voltage protection function of the power supply apparatus. Moreover, the extra energy would be released to the energy release unit after the testing of the over voltage protection function of the power supply apparatus is finished. Therefore, the energy releasing of the present invention is faster than the energy releasing of a related art.
