摘　　要：This paper studies the design and sizing of a filter (<em>L-C</em>) for an inverter with 180<span style="white-space:nowrap;"><span style="white-space:nowrap;">&#176;</span></span> control in Medium voltage (MV), based on formulas of the capacitance of the capacitor <em>C</em> and the inductance <em>L</em> of the filter (<em>L-C</em>) of an SPWM inverter. These formulas were obtained by minimizing two parameters: the reactive power of the capacitor (capped at 5% of the apparent power of the load) and the ripple of the current flowing through inductance <em>L</em> (capped at 10% of the current supplying the load). The application of these formulas for the calculation of the filter (<em>L-C</em>) of the 180<span style="white-space:nowrap;">&#176;</span> control inverter in MV is not conclusive. Studies have been carried out to make them applicable. The results show that limiting the current ripple in the inductor to 10% of the load current is a valid assumption and that limiting the reactive power of the capacitor to 5% of the apparent power of the load presents shortcomings. The results also show that setting the inductance <em>L</em> of the filter to <em>L_maxi</em>and the capacitor <em>C </em>from 35 × <em>C_maxi</em> to 400 × <em>C</em><em>_maxi</em>gives voltage and current THDs that meet the 519 IEEE-2014 standards.This paper studies the design and sizing of a filter (<em>L-C</em>) for an inverter with 180<span style="white-space:nowrap;"><span style="white-space:nowrap;">&#176;</span></span> control in Medium voltage (MV), based on formulas of the capacitance of the capacitor <em>C</em> and the inductance <em>L</em> of the filter (<em>L-C</em>) of an SPWM inverter.
