POB is Power Output Boost circuit. It was discovered by Ajibewa Irekanmi in Nigeria, 2020 during the COVID-19 lockdown. The idea came all about the researches on energy converters such as transformer, boost converter types , buck converter, charge pump, switch capacitor and inverter. His motive was to discover how Direct current could be boosted without change of energy different from previous devices such as the boost and buck converter. His own modification works on closed system switching to perform the boosting without breaking the laws of physics,
" Energy can neither be created nor destroyed ". But, here is what he found. A circuit design that helps power to be boosted with the help of a temporary storage device such as capacitor. The circuit contains the primary devices useful by the secondary devices with much importance such as the relay - SPDT. The relay switches via a NPN transistor, charging and discharging the power stored in the capacitor without losing any of it efficiency of connection. Meaning that when the following process of boosting occurs, the output is never disappointed in the input. And for boosting to occur, the capacitor charges in parallel and discharges in series between the input and the output in a closed system of constant switching.
During charging :
The relay switches to normal open of the relay pin connecting the capacitor charging and the output in parallel. Keeping voltage same, but current slightly different.
Because the capacitor is connected to a charged body. It only charges up to 63% of the power from the body and never discharges all of its power before switching takes place, and the capacitor reaches a state of equal charge from secondary input.
During discharging :
The relay is back at normal closed of the relay pin and power flows from the charged body through the capacitor keeping the current high and increasing voltage > than source due to the charged capacitor.
The power boosting is done mainly because of relay and capacitor's switching process through in and out of the device, while diodes and resistors are used in the circuit to help with modification of voltages and current values to give a better result. The circuit conveniently boost power more than 88% of not less than 10v input source on no attached load, and boost power to about or more than 50% on attached load.
Why capacitor aid boosting
During charging, the positive terminal of the Input source connected to one side of the plate makes it positive.
And during discharging, the positive input is now connected to the negative plate of the capacitor, making the input and capacitor in series like how batteries are connected normally in series to increase voltages and the current is stabilized because of the forward diode connection of input in parallel to the series connection of capacitor.
