Normally, for standard 220V AC household projects, a single 600V or 800V TRIAC is more than enough. But what if you are working with a very high voltage line, like 1000V AC? A single common TRIAC will immediately burn and short circuit because it cannot handle that much voltage stress. To solve this, we can […]

How to Connect Solar Panels in Series and Parallel
In this post we will study how to connect solar panels in series and parallel and also learn how to calculate solar panels in series and parallel. Before I have explained the connection details, it would be important for us to learn some of the important parameters and specifications related to solar panels. Solar Panel […]
How to Calculate Capacitors in Series and Parallel
Capacitors connected in series or parallel are very common in electronic circuits. This is done in order to achieve the desired capacitance value and also to make the performance of the circuit accurate. In the following post I have explained how to connect capacitors in series and parallel: Connecting Capacitors in Series When we connect […]
How to Connect Resistors in Series and Parallel
There are three ways to interconnect resistors: series, parallel and in combination of series/parallel. When resistors are joined in series, the current passing via one resistor also passes through the next. When resistors are joined in parallel, they are wired across each other, resulting in the same voltage across each resistor. When resistors are connected […]
Series 2S, 5S Li-Ion Cell Charger using BQ7718
This BQ7718 series 2S to 5S series Li-Ion cell charger is designed to monitor the voltage of each of the li-ion cells independently, with reference to an internally set reference level. As soon as any of the cell voltage tends to go above the reference level, it triggers an internal delay timer. This delay timer […]
