Question:

At present, switching power supply commonly used in high-power switch which?

For the specific parameters for the requirements (power: 350W or more working voltage: DC 300V) switch switch power supply which are commonly used? To say that there are specific places in Jinan where to sell? Anxious ~

Answer:

IGBT tube is the most commonly used IRGP20B60PD. MOS tube is the most commonly used IRFP450, IRFP460. Transistor is the most commonly used 2SK2850.
Are you going to IGBT tube? Can be commonly used are transistors and MOS tube.
Oh, you said the scope of some big. You use the circuit in different forms, switch the choice of very different.
