Abstract

The invention discloses a phase lead compensation network, a power supply converter and a closed-loop control system. The phase lead compensation network is arranged in the closed-loop control system of the power supply converter. The closed-loop control system also comprises a power supply converter and a control module, wherein the power supply converter receives input voltage, generates output voltage and feeds back the output voltage to the control module. The power supply converter comprises an inductor, wherein the power supply converter finishes energy transformation by controlling the current of the inductor; the control module inputs reference voltage and the output voltage of the power supply converter, generates a control signal to the power supply converter and is used for regulating the dynamic response of the power supply converter; and the phase lead compensation network is connected with the inductor of the power supply converter in parallel, and a phase lead network comprises a capacitor and a resistor which are connected in series. The invention can realize the detection of the current of the inductor of the power supply converter with low cost and high efficiency and enhance the stability of the closed-loop control system of the power supply converter.

Description

technical field [0001] The invention relates to a power converter, in particular to a phase lead compensation network, a power converter and a closed-loop control system of the power converter. Background technique [0002] A power converter is an electronic device that converts an input voltage into an output voltage using current conversion and / or rectification. Power converters include Buck (step-down) converters, Boost (boost step-up) converters, Buck-Boost (boost-boost step-down) converters, and AC / DC converters. Power converters usually include one or more inductors, and energy conversion is accomplished by controlling the inductor current. [0003] see figure 1 As shown, it is a circuit schematic diagram of a DC / DC boost converter in the prior art. The boost converter is used to convert the DC input voltage U i Converted to DC output voltage U o , and U o higher than U i , the boost converter includes inductor L, switch tube V, diode D, voltage stabilizing capa...
