Some high-end solutions even implement different types of capacitors to filter the power that is delivered to the CPU.MOSFETs, or Metal-Oxyd Semiconductor Field Effect Transistors, are basically tiny switches. Usually, by counting the number of inductors (chokes), you can determine how many phases VRM has.The number and type of capacitors does not follow any rule and is set by the manufacturer. The quality of the motherboard is often expressed by how many VRM phases it has.In the case of the CPU, the whole point of the voltage regulator is to take 12V from the 8-pin EPS connector and step it down to 1.2V (the stock voltage for most Intel CPUs), and that is done by pulsing the current trough each phase of the VRM.Schematics of an 8 phase VRM.This is a block diagram of a VRM that has eight true phases and the dashed line marks what is supposed to be one individual phase. A set of drivers, MOSFETs, chokes and capacitors make up a phase of the VRM. Please explain the operation of voltage-resonant soft switching of an IGBT. Please explain hard switching and soft switching using IGBTs. A MOSFET works by either letting current flow across its terminals or not depending on the voltage applied. This is happening through inductors, that are popularly called chokes, and capacitors. Please give some application examples for IGBTs. The final section of the VRM is where the filtering and voltage smoothing is done. The drivers and doublers are connected to the MOSFETs and they are all part of the power unit.
