This circuit is designed to charge between one and twelve NiCd cells using a car battery. With switch S1 set to the normal position, it is capable of charging up to six cells. The circuit operates by utilizing a car...
A very simple 5-volt constant voltage, constant current (CV/CC) universal-input power supply for cell phone or similar charger applications can be designed using the LNK616PG product from the LinkSwitch-II family. This low-cost charger adapter accepts a wide range of...
The previous version of this device used pulse width modulation (PWM) to control the power from the five solar panels to charge the battery bank. Under full sun conditions, the MOSFETs got a bit warm and the whole unit...
The circuit is actually a half-wave rectifier. It only charges the battery on every half cycle. The plug pack doesn't like this as it leaves residual flux in the core of the transformer and causes it to overheat. But...
The ultimate source of energy is the Sun. It is possible to generate current from sunlight using solar panels. These panels convert light energy into electrical energy. A solar panel consists of a number of solar cells, which produce...
Autotransformer voltage starting, with an adjustable starting time of 30-60 seconds. It includes the SDJ electrode liquid level sensor of HJ-13 type, a pump control system box of HKD-21B type, 1MK level modules adopted by HKG-1SG type, 2MK start...
