Abstract
The invention disclosed a method and system for multi-port synchronous high voltage testing, which mainly uses two or more sets of testing circuit with variable output condition and a high voltage generator with zero intermediate voltage for synchronous high voltage testing. Therefore it is not only possible to prevent operators from electric shock but also to provide correct multi-port testing voltages so as not to cause object under test damage. The testing circuit uses a plurality sets of individual high voltage generator and a current detector for providing functions for reading and determining individual voltage and current, so that it is possible to perform several high voltage tests during a single test period and complete tests on electric products. It is therefore possible to achieve both reduction of test-time and safety of operators.
