| Abstract: | By analyzing the voltage drop current sharing technology and the current drop current sharing technology, a formula about current sharing and voltage regulating is obtained, and a practical distributed DC switching power supply technology combined by the parallel current sharing technology and the current loop voltage supply technology is proposed based on the current loop technology. From the tests of a 5 kW distributed DC switching power supply system, it follows that the current sharing precision error is less than 3%, the dynamic response time under instantaneous full loads is less than 1 ms, the maximum voltage drop is less than 2%, the dynamic response time under instantaneous swing full loads is less than 5 ms, and the maximum overshooting voltage is less than 1%. It indicates that this method is effective and feasible. |
