Furthermore, different magnetic loads may require different amounts of capacitors to be used, and the system should only use as many capacitors as needed. Power transistors controlled by a micro controller will be used to coordinate the charging and discharging process.
The capacitors store energy and release it every cycle on an AC power distribution network to compensate for the fact that highly inductive loads such as electric motors draw a current which 'lags' behind the applied voltage.
You can think of a capacitor as an energy storage tank. Just like a water tank holds water, a capacitor holds energy. When we need the energy, similar to opening a tap, the capacitor provides it back to the circuit. Why Do We Need Capacitors? Capacitors play a crucial role in our everyday electronics and gadgets. Here’s why they’re important:
Capacitors consist of two metal plates with a material called a dielectric in between. When connected to power, these plates hold opposite electrical charges. Later on, the capacitor can release this energy into the circuit. You can think of a capacitor as an energy storage tank.
As you go to higher speed, inductance causes a bigger problem than resistance. The capacitor acts as a very close source of power. You pull your high speed power from the capacitor and the power source slowly charges the capacitor. When done properly, everything works to spec.
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
