I supose that my last setup will be enough for charging somwhere between 50ah batt and 100ah batt. This need to be prove in good condition battery. If the input lets say is a photovoltaic panel, the voltage will rise i suppose above 14volt. For this charger means that the voltge on cap will rise near 100volt at peak maybe more. Remember that the setup i use takes only 500mA at 11.4 volt. For bigger power needs i have made a aditional module that its consist in driver board with up to 3 fets driven by main board and one aditional pancake coil.I will exemple my kit by few pictures and 2 movie.
First movie is with power input , about 500mA
second movie is with charging voltage on battery
For unknown reason i can not take any scope reading because when i turned the system on my digital scope fail to aquire.So i stick with the old fashion voltmeter.
Finally ive got an broken solar panel, and ive mounted it and connect with 2 charger in parallel. It is working as i expected , at full sun thevoltage rise at 18v under load. The chargers works at peak voltage ,about 110 volts. Battery accept the charge very good. A battery i have 100Ah, starts to rise up and down the voltage. With other setup that ive made i bearly move the voltage. Unfortunatelly the solar panel is not mounted on the roof and the peak voltage is only few hours. BUT the charger start to discharge potential in the battery at ONLY 5 VOLT from the panel.So the battery will recieve charge even in cloudy days or shadow.
Here it is. final product that is designed to work either with solar panel ,or with fixed voltage. when work with solar panel it will automatic track the voltage means that at full sun the charger will increase the number of pulse and decrease the pulses when little sun is available. the other advantage i use is that capacitor when charged with magnetic field colapse exibit an fenomena that i will call self charging. so i could increase the output of energy by decreasimg the input. that is amazing.
