Power supply digital control development platform

Abstract

The invention discloses a power supply digital control development platform which comprises a platform external interface, an input signal conditioning circuit, a power drive output circuit, a switch control output circuit and a DSC minimum system, wherein the platform external interface at least is taken as an interface between an input signal and an output signal of the development platform; the input signal conditioning circuit correspondingly and adaptively conditions a power supply analog signal and a binary signal form the platform external interface; the power drive output circuit outputs power transistor switch control signals computed and output by the DSC minimum system to the platform external interface after the power transistor switch control signals are subject to adaptive drive capability treatment; the switch control output circuit outputs the switch control signals computed and output by the DSC minimum system to the platform external interface after the switch control signals are subject to adaptive treatment; the DSC minimum system is taken as a carrier of embedded software through taking DSC as a core processor during the development to bear the operating environment of the embedded software. The invention realizes the full-digital control and has strong expansibility and good control performance.

Description

technical field [0001] The invention relates to a development device for a digital power supply, in particular to a development platform for digital control of a power supply. Background technique [0002] With the trend of energy shortage and environmental deterioration, environmental protection has become a focus of global attention.
