This paper describes the hardware and software to implement the project in detail and explains how the circuit characteristics influence the measurement error and how to processing the data 本文詳細(xì)敘述了實(shí)現(xiàn)模擬中頻方案的硬件電路和軟件系統(tǒng),說明了場(chǎng)強(qiáng)儀中各種電路特性對(duì)測(cè)量精度的影響以及對(duì)場(chǎng)強(qiáng)儀進(jìn)行數(shù)據(jù)標(biāo)定的方法。
The characteristics of the full bridge series resonant converter with the separate transformer are analyzed . the resonant frequency and other circuit characteristics are discussed . the full bridge series resonant converter is analyzed by circuit simulation 對(duì)帶可分離變壓器的全橋串聯(lián)諧振變換器的電路特性進(jìn)行了分析,分析了變換器的諧振頻率,利用正弦等效的方法分析了變換器的電路特性,對(duì)雙極性控制和移相控制全橋串聯(lián)諧振變換器進(jìn)行了電路仿真。
To make use of parasitic parameter to design the circuit : because parasitic inductance induced by packaging could not only influence the circuit characteristics , but also lead to a design failure , the inductor value needed in the circuit can be designed in the amplifier according to the size of parasitic inductance 4 、利用寄生參數(shù)來設(shè)計(jì)電路。由于電路的封裝存在寄生電感,其不僅會(huì)影響電路的特性,而且可能造成電路設(shè)計(jì)工作的失敗,所以根據(jù)電路所需電感及其值的大小,將之有效的設(shè)計(jì)在放大器電路中。
