升压型直流-直流转换器
摘要：
本发明提供一种升压型直流‑直流转换器，包括：升压电路、保护电路、检测电路、反馈控制电路和反馈电路；所述升压电路经由所述保护电路向外部输出电压，所述保护电路根据所述升压电路的输出电流，控制所述升压电路向外部输出的电压；所述检测电路检测所述保护电路的输出电压，并根据检测的输出电压控制所述反馈控制电路是否根据所述反馈电路的反馈电压对升压电路进行反馈控制。所述升压型直流‑直流转换器通过增加保护电路和检测电路，实现输出短路时完全关闭输出，达到短路保护和减小电能消耗的效果。
摘要（英）：

The present disclosure discloses a DC to DC boost converter, comprising a boosted circuit, a protecting circuit, a detecting circuit, a feedback control circuit, and a feedback circuit. The boosted circuit outputs voltage to the outside through the protecting circuit, the protecting circuit controls the boosted circuit to output voltage to the outside according to the current output from the boosted circuit. The detecting circuit detects the output voltage of the protecting circuit and controls whether the feedback control circuit proceeds the feedback control to the boosted circuit according to the feedback voltage of the feedback circuit or not according to the detected output voltage. The DC to DC boost converter adds the protecting circuit and the detecting circuit, which completely shuts the output down while the output is short, thus achieving short-protecting circuit and reducing power consumption.
