Circuit design is a combination of technical knowledge and understanding to each device parameters. Each device parameters are defined in the datasheet. Therefore, knowing how to read MOSFET datasheet is a must in circuits involving MOSFETs. In this another article, in order to explain the ideas clearly, let us use an actual MOSFET part from Infineon. The parts number is IGLR60R190D1XUMA1

Diode is very important integral part of a buck converter. It is very popular than using a switch in the same location. A diode does not need a control mechanism while a switch needs. A diode is cheaper than a switch considering there is an added control mechanism. Here are the guides on how to select a buck converter diode.

Before going to the discussion on how to select a transformer, let us cover first some of the transformer basic fundamentals. Transformer is could be a low frequency like those used in 50Hz or 60Hz line. Transformer is could be a high frequency one like those used in switching mode power supplies. Transformer will transfer power from the primary to

Diode has many uses. It could be as a rectifier, a reverse blocking device, a component in a switching converter or in a switching power supply and so on. Regardless, what application it is, they are the same parameters to consider. These parameters are all given in the diode datasheet. If you are looking for guidance on how to select

IGBT has two types of losses. One is conduction and the other one is switching. Conduction loss is due to the voltage drop between collector and emitter times the collector current. On the other hand, switching losses is due to the dynamic parameters of the IGBT. If you are looking for an explanation on how to derive IGBT power losses,

P-Channel MOSFET is not popularly known compared to the N-Channel variant. Others said it is because difficult to deal with while others are saying it is not supply abundant and there are others saying that it is only limited to few applications. In this article, I will concentrate to the last reason, about applications. So, stay with me as I
