How to Calculate Solar Panel, Inverter, Battery Parameters
In this post I have explained through calculations how to select and interface the solar panel, inverter and charger controller combinations correctly, for acquiring the most optimal results from the set up. Calculating Solar Panel, Inverter and Battery Charger Specifications For the sake of convenience, let’s believe you possess a a 100 watt appliance or […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
Simple Online UPS Circuit
In this post I have explained about the making of a simple online uninterruptible power supply (UPS) which guarantees a seamless transfer of AC mains supply to inverter mains supply for the load, due to the absence of cumbersome transfer switches or relays. What is an Online UPS As the name suggests, an online UPS […]
Universal H-Bridge Circuit Module
In this article I will elucidate a simple universal H-bridge module using BJTs and N-channel MOSFETs. This module can be integrated with any standard oscillator ICs such as IC 4047 or IC SG3525 or even IC 555, to create a highly efficient H-bridge inverter circuits. Why using 4 N-channel MOSFET H-Bridge is the Most Efficient […]
Automatic Micro UPS Circuit
The following article discusses a simple automatic micro UPS circuit which can be used with modems for acquiring uninterrupted power from a DC source, and battery during mains power failures. The circuit also incorporates an automatic over charge cut off, and a low battery indication feature. The circuit was requested by Mr. Kapil Goel. Technical […]
