| Zusammenfassung: | Disclosed is a cell simulator which comprises a three-phase power frequency transformer, a drive circuit, a controller, and a three-phase PWM converter. The three-phase power frequency transformer has a primary side which is used for connecting a power grid, and a secondary side of the three-phase power frequency transformer is connected with the alternating-current side of the three-phase PWM converter. The direct-current side of the three-phase PWM converter is connected with a load. The drive circuit is electrically connected with the three-phase PWM converter and the controller. The controller is connected with a direct-current side voltage sensor and a direct-current side current sensor of the three-phase PWM converter, and an alternating-current side voltage sensor and an alternating-current side current sensor of the three-phase PWM converter. The controller collects voltage and current signals of the direct-current side and the alternating-current side of the three-phase PWM converter. The three-phase |
