Research on the Application of New Active Inverter Technology in Battery Maintenance

Abstract:

This paper presents a discharge inspection method based on new active inverter feedback discharge after comparison with the check discharge from pure resistance of power station batteries. A new active inverter system has been developed with SPWM pulse width modulation technology, which is based on DC/DC circuitry, along with a three-phase full bridge inverter and control topology circuits. In addition, the principle for selecting the parameters of RCL elements of the system has been analyzed. This paper also presents a detection method combining active detection with passive detection for the islanding effect which exists in the grid-connected discharge system, according to the islanding effect of grid-connected discharge equipment, so as to stably discharge without interference on the grid.
