How To Use Triac For AC Power Control
Here we are talking about controlling things like lamps, motors, heaters, and other similar electrical loads. The devices we use for this purpose are called thyristor and triac, OK? Both these devices, thyristor and triac, they can actually do this job like simple switch ON/OFF or they can also adjust the power given to these […]
Adjustable Switching Power Supply Circuit – 50 V, 2.5 Amps
The explained variable switching power supply circuit is designed around the integrated switch mode power supply controller device Type L4960 from SGS. The main features of this switching regulator can be summarized from the following data: Main Features Input voltage range: 9-50 VDC Output voltage variable from 5 to 40 V. Maximum accessible output current […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
How to Repair a Switch-Mode-Power-Supply (SMPS)
In this post we try to diagnose a burnt SMPS circuit and try to troubleshoot and repair the circuit. The shown unit is a cheap readymade Chinese make SMPS circuit. This article is written as per the request made by Mr. Kesava. My SMPS got Burnt The below attachment is 12v 1.3 amps SMPS for […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]
