Vo wsem mire sowremennoe sel'skoe hozqjstwo, osnowannoe na primenenii himikatow, samo po sebe igraet bol'shuü rol' w uhudshenii zdorow'q pochwy, prioritetom kotoroj wsegda qwlqetsq tol'ko wysokaq urozhajnost'. V sel'skohozqjstwennoj sfere uzhe nakopleny obshirnye znaniq o degradacii pochw. Tak, chrezmernoe ispol'zowanie sinteticheskih udobrenij, sistematicheskaq wyrubka lesow, äroziq pochwy iz-za wysokoj obrabotki i wozdejstwiq dozhdej i wetrow, poterq organicheskogo weschestwa i rqd drugih faktorow priweli k usileniü opustyniwaniq, potere millionow tonn plodorodnoj pochwy i, koswenno, zailiwaniü rek i ozer, wyzwali zasolenie pochwy, izmenenie klimata i poterü bioraznoobraziq. Pomimo neobhodimosti postoqnnogo monitoringa i ocenki fiziko-himicheskih i biologicheskih processow dlq dostizheniq luchshego sostoqniq pochwy, neobhodimo pomnit', chto organicheskie weschestwa pochwy qwlqütsq osnownymi uchastnikami krugoworota pitatel'nyh weschestw, a takzhe nahodqtsq w slozhnom wzaimodejstwii s rasteniqmi.

In the recent times, Multilevel Inverter (MLI) Technology is constantly evolving in the research area of high voltage with high power energy control. Various modulation schemes have emerged for its control. In this work, Phase Disposition (PD) modulation technique, which is a type of MCPWM technique, has been implemented to improve the output voltage waveform of a five level diode clamped multilevel inverter.
