Working principle of invertor

Answer 1

If you have a high input going into the inverter it will have a low output and if you have a low input going into the inverter it will have a high output, the bottom line is it's output is the opposite of the input.

Answer 2

The answer depends in which context you're asking. In digital electronics, an inverter simply inverts a single digital signal. Its symbol is a triangle, with a circle at the point (so it is actually a buffer with an inverted output). So if a logic-high (1) is present on the input, a logic-low (0) will be present on the output, and vice-versa. In power electronics, an inverter is simply put, a DC to AC converter. It uses an SCR or IGBT driven with PWM (Pulse-Width Modulation) followed by a low-pass filter to synthesize simple AC sinusoids or more complex waveforms. A typical application of this is a UPS (Uninterruptible Power Supply). When the AC power fails, the DC batteries are used to form an AC signal very similar to the mains power, and can drive consumer electronics for a finite period of time. An industrial application is a VFD (variable frequency drive) for induction motors. Induction motors spin at a fixed velocity relative to the incoming AC frequency. To allow for variable-speeds of these motors, a VFD, or inverter is used. In this device, the incoming AC power (single- or three-phase) is rectified to high-voltage DC. Then, an AC output is generated, whose frequency is proportional (more or less) to the desired rotational velocity of the motor. See the Wikipedia links for great information.

Answer 3

The invertor is a dual circuit electric gadget that uses electronic devices to convert high volt A.C current to a low volt trickle charging current converting transformer (step down) converted by a semi conductor as D.C current to charge a high capacity battery cell . The reversal circuit employs a step up transformer to first change the low voltage D.C current to high volt and then converts it to A.C current by IC devices.

Answer 4

Converts DC to AC.
