In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. You can download the IR2110 datasheet from the IR website. Here's the download link: www.irf.com/product-info/datasheets/data/ir2110.pdf First let’s take a look at the block diagram and the pin assignments and pin definitions (also called lead assignments and lead definitions): Fig. 1 - IR2110 block diagram (click on image to enlarge)...
Hello guys. Today I will guide you how to make a Digital Thermometer Circuit using IC DS18B20 and PIC 18F4550. I also provide you the source code of this project. Thank you for reading my blog :)
On different forums, I often find people asking for help in calculating the required turns for a ferrite transformer they are going to use in high-frequency/SMPS inverters. In a high-frequency/SMPS inverter, the ferrite transformer is used in the step-up/boost stage where the low voltage DC from the battery is stepped up to high voltage DC. In this situation, there are really only two choices when selecting topology – push-pull and full-bridge. For transformer design, the difference between a push-pull and a full-bridge transformer for same voltage and power will be that the push-pull transformer will require a center tap, meaning it will require twice the number of primary turns as the full-bridge transformer. Calculation of required turns is actually quite simple and I’ll explain this here. For explanation, I’ll use an example and go through the calculation process. Let’s say the ferrite transformer will be used in a 250W inverter. The selected topology is push-pull. The power source...
