Multifunctional portable silicon carbide device characteristic tester

A multifunctional portable silicon carbide device characteristic tester disclosed by the present invention comprises a high-voltage direct-current power supply and a double-pulse test unit, the high-voltage direct-current power supply is electrically connected with the double-pulse test unit, and the high-voltage direct-current power supply comprises an AC/DC charging module, an electrolytic capacitor and a discharge resistor which are connected in parallel. Wherein two ends of the AC/DC charging module are respectively connected with a direct current power supply and an alternating current power supply through a direct current power supply interface and an alternating current power supply interface, and a charging current-limiting resistor is also arranged between the AC/DC charging module and the electrolytic capacitor; the multifunctional portable silicon carbide device characteristic tester can be used for verifying the conduction characteristic, the turn-on/turn-off characteristic, the reverse recovery c
