SpletTo design the inductor and choose an inductor value, we generally will try to limit the amount of switching ripple in the inductor current. How much ripple we allow is a design choice and at least for the next several weeks, we will discuss converters where this ripple is limited in value to maybe 10 or 20 percent of capital I at full power. Okay. Splet21. okt. 2024 · In a switching power supply, there are four types of rectifier circuits: 1# Bridge Rectifier—AC main to DC pulse Normally, we will find this rectifier circuit at the input side of the switching power supply as in the circuit diagram below.
