In this post I have explained how just a single IC MBI6001 can be used as a transformerless constant current LED driver circuit for illuminating a chain of many LED in series. The MBI6001 series of ICs are designed to work with mains AC inputs and convert it into a lower voltage DC output which […]

Transformerless UPS Circuit for Computers (CPU)
In this post I have explained how to build a simple UPS circuit for backing up computers or PCs during sudden power failures or brownouts. Introduction Normally when we talk about uninterruptible power supplies (UPS) we imagine large inverter units with complex features, where it imperatively needs to be a pure sine wave type. Such […]
