Last edited by … WebA power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.. The input voltage, output … WebThis is known as the peak or crest value of an AC waveform: Figure below Figure 1. The peak voltage of a waveform. Another way is to measure the total height between opposite peaks. This is known as the peak-to-peak (P-P) value of an AC waveform: Figure below Figure 2. Peak-to-peak voltage of a waveform. order country ham
