Theworking principle of the DC generatoris based on Faraday’s laws ofelectromagnetic induction. When a conductor is located in an unstable magnetic field, an electromotive force gets induced within the conductor. The induced e.m.f magnitude can be measured from the equation ofthe electromotive fo...
因此,为使谐振变换器工作在直流变压器(DC Transformer, DCX)模式,实现谐振工作点处的优化设计,通常需要引入一个额外的结构简单、易调节的DC-DC变换器实现动态闭环调压能力。调压变换器的引入会增加系统损耗,因此需通过合理的参数设计令调压变换器在整个工作范围内处理小部分系统功率,从而有效地减小该部分的损耗占比,...
The working principle of a basic DC power supply circuit involves several stages. The first stage is the AC input stage, where the AC voltage from the main power supply is connected to the power supply circuit. This stage typically involves a transformer to step down or step up the voltage...
