【摘要】 本文推出一种新型的高效正弦波逆变器－－单片电压比较跟踪桥式放大（ＳｉｍｐｌｉｆｉｅｄＶｏｌｔａｇｅ－Ｃｏｍｐａｒｉｎｇ－Ｔｒａｃｋｉｎｇ－ＢｒｉｄｇｅＡｍｐｌｉｆｙｉｎｇ）逆变器，简称ＳＣＴＡ（Ｂ）逆变器。它是ＳＣＴＡ逆变器的改进形式。该逆变器无输出变压器，却能将开关电路与放大电路巧妙地结合，获得高效优波的逆变效果。本文还分析了基于ＣＴＡ逆变机理的几种逆变器，使读者从中了解ＣＴＡ变流技术之概况。更多还原

【Abstract】 A new kind of sine wave inverter with high efficiency,that is,the Simpli-fied Voltage-Comparing-Tracking-Bridge Amplifying Inverter,of SCTA(B)Inverter,was presented.The SCTA(B)Inverter is he improving ones of SCTA Inverter,andneedn’t the output transformer,but it could realize the proper connection of switch circuitwith amplifying circuit,and obtain the effect of high efficient and high quality wave. In this paper,several kinds of inverter that based on the principle of CTA were alsoanalysed。The readers could find out the current development of CTA inverting techniquesfrom the analyses.更多还原
