How to replace diode rectifier circuit with rectifier bridge

How to replace AC220V with DC390V rectifier diode circuit with rectifier bridge? In fact, there are formulas for calculating parameters in circuits, which requires a certain understanding of diodes.

Bridge rectifier circuit: Uo=0.9Ui=198 (V)

If there is a capacitor filter and the filtering capacitor is large enough: Uo=√ 2Ui ≈ 311 (V)

That is to say, if LZ only converts AC220V into DC through a rectifier bridge, the output voltage can only be between 198-311.

To achieve the goal of LZ, two methods are usually used: one is to increase the input voltage with a step-up transformer (as low as 390/√ 2 ≈ 276V); The second is to first rectify and then use the switching power supply circuit to raise the voltage to 390V.

The circuit of replacing the diode with a rectifier bridge is completed, of course, the parameters must be controlled very strictly.
