Battery Charger for Positive Earth Cars
The post presents an 6v or 12v battery charger circuit for positive earth cars which could be used for upgrading 6V positive earth cars, facilitating an external 12V battery to be used in them along with the existing 6V battery with a common positive earth body. The idea was requested by Mr. Joe Ceretti. 6V […]
Make this EV Battery Charger Circuit
In this post I will explain how to build and test a homemade yet very professional looking high power EV battery charger transmitter circuit using H-bridge fixed-frequency AC inverter topology, driving a series-resonant LC tank. I will also explain how to build a complementing EV charger receiver circuit for receiving the charging current from the […]
How to Make Powerful Car Headlights Using LEDs
In this post we see how to build an enhanced and efficient car headlight lamp using Pirhana LEDs. A car LED headlight is a powerful lamp built using high efficiency LED arrays, which creates extremely powerful headlight lamp for the car, along with a very high efficiency in terms power consumption. Using 4-pin Pirhana LEDs […]
