基于STC电路与谐振Buck电路的降压变换器
摘要：
本发明的基于STC电路与谐振Buck电路的降压变换器涉及一种降压DC/DC变换器，该的基于STC电路与谐振Buck电路的降压变换器包括谐振Buck电路和STC电路，其中，谐振Buck电路与STC电路的输入侧串联、谐振Buck电路与STC电路的输出侧并联，且谐振Buck电路工作在闭环控制模式，令输出电压闭环控制；STC电路工作在不控模式，令电压变比的增益固定。
摘要（英）：

The invention discloses a buck converter based on an STC circuit and a resonance Buck circuit, and relates to buck DC/DC converters. The buck converter based on the STC circuit and the resonance Buckcircuit comprises the Buck circuit and the STC circuit, wherein the resonance Buck circuit is connected with the input side of the STC circuit in series; the resonance Buck circuit is connected with the output side of the STC circuit in parallel; the resonance Buck circuit works in a closed-loop control mode, so that an output voltage is subjected to closed-loop control; and the STC circuit worksin an uncontrolled mode, so that the gain of the voltage transformation ratio is fixed.
