The selection of circuits and devices focuses on maintaining low DV/DT and DI/DT levels, as many circuits reduce radiation by minimizing these values. This also alleviates stress on the switching transistors. These circuits include ZVS (Zero Voltage Switching), ZCS (Zero Current Switching) resonant mode, (a type of ZCS), and SEPIC (Single-Ended Primary Inductor Converter).

Decreasing the switch time doesn't necessarily guarantee progress in work, as the RF oscillation of magnetic components requires significant loss buffering, which can be observed as a continuous weakening of the return. While using software switching technology may slightly reduce efficiency, it offers significant advantages in cost savings and reduced space occupied by filtering/shielding.

3. There's always a tangle of power cables around the equipment, so staff must have a clear understanding of electrical knowledge. Most companies hire individuals with some knowledge in this area. Staff must pay close attention to electrical knowledge, as there can be no mistakes. The selection of components and circuit design are both crucial.
