Application of SPWM Bidirectional Converter Technology in Emergency Power Supply

Inhalt:
This paper analyzes the design points of the overall content of emergency power supply, The content includes the working principle, bidirectional DC / DC circuit, SPWM inverter, etc, Combined with the specific process of SPWM bidirectional converter technology in emergency power supply, the contents include A/D sampling, judging working state, discharging module management, charging module management, etc. By studying the converter control strategy, grid-connected operation control strategy, island operation control strategy, midpoint potential balance control strategy, it is also demonstrated in an experimental way, the aim is to improve the cognitive level of SPWM bidirectional, Ensure the operating stability of the emergency power supply.
