In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]

H Bridge Inverter Circuit using IC SG3525 and MOSFET IRFZ44N
This article explains an H-Bridge inverter circuit based on the SG3525 IC and MOSFETs like IRFZ44N or IRF3205 or IGBT like GT50JR22, which can convert DC to AC with a frequency of 50Hz or 60Hz, suitable for most standard applications. The SG3525 is a widely used PWM (Pulse Width Modulation) controller IC designed for various […]
What Are Optoisolators and Optocouplers, How Do They Work?
Optoisolators and Optocoupler sound very similar and they are the same in terms of workings and other features let’s see what are optoisolators and optocoupler. There are some differences due to which they are given different names. Photocoupler is another name of the optocoupler. An optocoupler or photocoupler and an optoisolator are semiconductor devices that […]
Diac Symbol, Construction, VI Characteristics and Applications
The Diac is basically a two-terminal device. Here we will discuss the symbol, construction, VI characteristics, advantages, disadvantages and applications of Diac. It is such a combination of semiconductor layers that allows triggering in both directions. The Diac is used as a triggering device for the TRIAC circuits. What is a DIAC? A DIAC (Diode […]
