How to Design a Solar Inverter Circuit
When a DC to AC inverter is operated through a solar panel, it is called a solar inverter. The solar panel power is either directly used for operating the inverter or it’s used for charging the inverter battery. In both the case the inverter works without depending on mains utility grid power. Designing a solar […]
SPDT Relay Switch Circuit using Triac
An efficient solid state single pole double throw or SPDT switch can be built using triacs for replacing a mechanical SPDT. In this post I have explained a simple solid state triac SPDT relay circuit, using an optocoupler and a couple of triacs, which can be used as an effective replacement for mechanical relays. The […]
How to Design an Uninterruptible Power Supply (UPS) Circuit
In this brief tutorial I have explained how to design a customized UPS circuit at home using ordinary components such as a few NAND ICs and a some relays. What is an UPS UPS which stands for uninterruptible power supply are inverters designed to provide a seamless AC mains power to a connected load without […]
