系统加热可能带来电流的增加，这与光电导率测量非常相似。
System heating can cause a rise in cur-rent, much as it does in photoconductivity measurements.
由于这种控制方式具有响应时间快，稳定性高，内在限流保护等特点，因此近年来电流模式控制方式在电源管理芯片中得到了广泛的运用。
Due to its characteristics of fast response, good stability, inherent current limiting, current-mode controller has been widely applied in power management circuits.
