AI Technical Summary
Existing bidirectional conversion energy routers require at least four resistors to charge and discharge the bus capacitors on the high-voltage and low-voltage sides, resulting in high costs and large space requirements.
A charging and discharging circuit is adopted, which realizes the charging and discharging of the high-voltage side and low-voltage side bus capacitors through a charging and discharging module. By switching the conduction state of the charging and discharging module, the number of components is reduced, the cost is lowered, and the space is reduced.
It enables high-voltage side startup, low-voltage side startup, high-voltage side bus capacitor discharge, and low-voltage side bus capacitor discharge to be completed with only one charging and discharging module, reducing the number of components, lowering costs, and reducing the space occupied.
