The “let through” energy from the varistor will be further clamped by the TVS diode to a level that the circuit can survive. Littelfuse has many options for fuses, MOVs and TVS diodes, based on form factor, space

Applications Example A 1.44 W Universal Input Buck Converter The circuit shown in Figure 5 is a typical implementation of a 12 V, 120 mA non-isolated power supply used in appliance
AN-2162Simple Success With Conducted EMI From DC- DC ...
www.ti.comports. In another words, with the same power level buck converter, lower input voltage means higher input current, thus worse input conducted EMI. Compliance with conducted EMI standards usually requires the addition of a low pass filter between a switching-modepower converter and the input power source. Typically this is a passive LC filter ...

Finally, through simple control methods, regulation over many magnitudes of output power is possible while maintaining high e ciency. A complete, detailed methodology for SC converter analysis, optimization and imple-mentation is derived.
AND9957 - On Board Charger (OBC) Three-phase PFC …
www.onsemi.comThree-phase PFC Converter AND9957/D Summary With the coming electrification of the automotive market, the need of battery chargers is more and more demanded. With the simple equation more power, shorter the recharge time is, a 3−phase supply is here considered which can provide up to ‘3x’ the power of a single−phase supply.
