| titleOfInvention | Soft-cutting measuring circuit and measuring method for dynamic resistance of gallium nitride power tube |
| abstract | The invention provides a soft-switching measuring circuit and a measuring method for dynamic resistance of a gallium nitride power tube, wherein the soft-switching measuring circuit comprises the following steps: the main circuit is connected between the drain electrode and the source electrode of the tested gallium nitride power tube and comprises a high-voltage output circuit and a low-voltage output circuit which are connected in parallel; a high-speed drive circuit for providing drive voltage to the grid electrode of the gallium nitride power tube to be tested; the synchronous program control circuit is used for respectively providing synchronous control signals with set time sequences for the high-speed drive circuit, the high-voltage output circuit and the low-voltage output circuit and controlling the drive voltage, the high voltage and the low voltage to be synchronously supplied and disconnected according to the time sequences; and the voltage sampling circuit is connected in parallel with the two ends of the drain electrode and the source electrode of the tested gallium nitride power tube. The invention can realize fast high-low voltage switching, support synchronous control of a plurality of time sequences and effectively measure the dynamic resistance of the gallium nitride power tube under the dynamic working condition. |
