The Switch Control of Double-Power Supply System Based on Intelligent Static Switch

Abstract:

This article introduces the principle of achieving high precision switch control on double-power supply system of electric fence power & inverting power by intelligent static switch with DSP-TMS320LF2407A as the main control chip and its hardware & software characteristics. The most central part of intelligent static switch is to embed an intelligent soft management system and set up a platform to manage other software, which achieve fast data processing and complex Boolean calculation of system. The intelligent static switch can monitor the magnitude, phase and frequency of electric fence power & inverting power in real time according to present parameter, revise the frequency & phase of standby power in-phase signal which is in a warm-waiting state, make sure they are highly precise in double-power supply system, and achieve “seamless” switch.
