• Nominal power: the power that can be supplied by the inverter in a continuous
way
• Overloading: the ability of the inverter to deliver a power that is considerably
higher than the nominal, as well as the time that this situation can be maintained
• Distortion waveform: the effective voltage and frequency of the output waveform
• Efficiency: the ratio, usually expressed as a percentage, between the output and
the input powers. It is dependent on the loading conditions, that is, on the total
power of the consumer devices
