The Circuit Question I stumbled upon your blog and I love it! So much great information and great ideas Right now I am trying to figure out […]
Mains 20 Watt Electronic Ballast Circuit
In this post I have explained a simple 20 watt fluorescent ballast circuit using a single chip FAN7711 from Fairchild semiconductor. The proposed mains 220V operated, 20 watt fluorescent ballast circuit is built around an LCC resonant tank and a half-bridge network. Implementing Zero Voltage Switching The main features and operations may be understood with […]
Making a 10/12 watt LED Lamp with 12 V Adapter
In this post I have explained the construction of a homemade 10 watt LED lamp using ready made 12 V SMPS adapter. The project was successfully built by Mr. Debabrata Mandal. In many of previous posts I have discussed the use of 1 watt white LEDs for making high efficiency LED lamps for implementing in […]
