Solar Based Power Bench for Physics Laboratory

Dinesh V Kala

Abstract: Most of the circuits in the physics laboratory runs on fixed or adjustable regulated DC power supplies. For example TTL based gates runs on 5V, Transistor based & 555 timer based circuits can easily run on 15 V regulated supply, Op-Amp based circuit?s needs ? 15V supply and so on. However, all these supplies are derived on the same concept.220 V AC utility is reduced to lower value of AC voltage using transformer which in turn is converted to regulated DC voltage. In this research work we have entirely different approach, we store the energy from the photovoltaic solar panels to a 12 V 26Ah battery and in turn run all the electronic circuits may be TTL based, may be transistorized based, may be 555 timer based or may be Op-Amp based all are running on the Solar Based DC Supplies.
