Circuit de suralimentation haute fréquence haute puissance fait maison - utilisant NE555
We’ve all come across pesky situations where we need a slightly higher voltage than our power supplies can provide. We need 12 volts but have only a 9-volt battery.
Or maybe we have a 3.3V supply when our chip needs 5V. That too, in most cases, the current draw is quite decent, we can achieve it by boosting the converter.
A boost converter is a DC-to-DC power converter that steps up voltage while stepping down current from its input supply to its output load.
It is a class of switched-mode power supply containing at least two semiconductors a diode and a transistor and at least one energy storage element: a capacitor, inductor, or the two in combination.
To reduce voltage ripple, filters made of capacitors sometimes in combination with inductors are normally added to such a converter’s output load-side filter and input supply-side filter.
