Beschreibung
Zusammenfassung:	The invention discloses a test circuit and method for a switch-on-only and switch-off-only test of a direct-current electric appliance, and the method comprises the steps: S1, carrying out the switch-on-only test of the direct-current electric appliance, and judging whether the switch-on-only test of the direct-current electric appliance is qualified or not in the test process; and S2, carrying out a breaking-only test of the direct-current electric appliance, and judging whether the breaking-only test of the direct-current electric appliance is qualified or not in the test process. According to the test circuit and method for the connection-only and disconnection-only test of the direct-current electric appliance, a test system which operates efficiently and can achieve connection-only and disconnection-only test of the direct-current electric appliance is provided, the detection quality and the detection efficiency of products are improved, a traditional accompanying test object is replaced by the IGBT, the
