Figure 11 c shows the active and reactive power waveforms of the inverter, which are 50 kW and 0var, respectively. It can be found out that the effective suppression of the DC component leads to the limited fluctuation in the fundamental frequency of power. Waveform of grid-connected current and power
Electronic inverters can be used to produce this kind of smoothly varying AC output from a DC input. They use electronic components called inductors and capacitors to make the output current rise and fall more gradually than the abrupt, on/off-switching square wave output you get with a basic inverter.
IEEE Spectrum, February 6, 2014. Inverters waste energy converting DC power to AC, and there are plenty of other losses in power generation and distribution, so why not simply supply low-voltage DC power to homes to begin with?

The total harmonic distortion of the load current is less than 4 %, and the dynamic response time is 0.3 s. 1. Introduction The inverter is classified into the voltage source inverter (VSI) and current source inverter (CSI) based on the characteristics of the DC power supply (Torres et al., 2020).
