Hi,
I am doing a research project on inverters I have extremely little understanding about them all I know is they convert DC to AC. My question is how does it use electromagnetic induction?
Thanks!
In: Physics
Inductors work by storing current in a magnetic field. When the power is removed, the magnetic field dissapates, but continues to feed current in to the circuit until the magnetic field is gone.
Its similar to how a capacitor holds a voltage charge, however the frequency cutoffs are backwards, so it acts like a low pass filter instead if a high pass filter, and inductors buffer current where capacitors buffer voltage. Where capacitors give a quick zap, inductors build up slowly and discharge slowly in comparison.
Using a few switching transistors to turn power on and off rapidly produces a digital square wave. That can be harsh on AC devices as the circuit jumps right to max current instantly, held there, and removed instantly. Most AC decices prefer more of a sine wave of AC power, so the inductor allows the power to fade in and out smoothly as the inductor is charged and discharged during the “on” phase, and is only at peak current momentarily during the cycle.
Hope that points you in the right direction.
