Inverter circuit for converting direct voltage (DC) into alternating voltage (AC) of household type and frequency, whose curvature is not rectangular, but extends obliquely, approximately as sine curve, for use in buses, boats, trains
摘要
<p>Inverter for DC to AC voltage conversion provides AC voltage with curvature not of rectangular shape, but extending obliquely approximating sine curve.There are capacitors (C20/C15) at operational amplifier (1) and capacitors (C21/C16) at second operational amplifier (2) reducing velocity of flank rise. Direct capacitive negative coupling affects partly flank steepness via capacitors C20 at first amplifier, and C21 at second amplifier.</p>
