The popular LM317 voltage regulator IC is designed to deliver not more than 1.5 amps, however by adding an outboard current boost transistor to the circuit it becomes possible to upgrade the regulator circuit to handle much higher currents, and upto any desired levels. You might have already come across the 78XX fixed voltage regulator […]

Gel Cell Battery Charger Circuit [Constant Current, Constant Voltage]
In this post I have explained what are gel cell batteries and also learn how to build a specialized charger for charging a gel cell battery, with full calculations. The proposed circuit works in two modes: it starts charging a discharged gel cell battery with constant current, until the full charge voltage is reached across […]
What is Constant Current Source – Facts Explained
In this post I will try to analyze what is constant current source and how it affects a load, or how it may be used with a load correctly for achieving the most efficient results. The following discussion between me and Mr. Girish will clearly explain what is CC or how constant current operates. How […]
Constant Current Generator Circuits Explained
Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]
High Current Triac BTA41/600B – Datasheet, Application Note
Triacs are one of the most important active electronic components which are exclusively used for power switching applications, these devices are especially suited to AC mains loads, and are able to switch large currents consistently. Triacs are the solid state replacements to mechanical relays, and come configured as static relays. The modern triacs today are highly sophisticated […]
How to Connect LM338 IC in Parallel to Increase Output Current
The LM338 is an adjustable 3-terminal positive voltage regulator capable of providing up to 5 amperes of output current. To increase the output current capability, you can connect multiple LM338 ICs in parallel. When you connect them in parallel, each IC will share the load current, allowing you to achieve higher total current handling capacity. […]
