摘要
DCBM10A电压缓冲装置必须在规定的时间内为后继负载提供持续电能,精确计算装置放电起止时刻非常重要。首先通过理论推理建立了电容放电的状态方程。接着介绍了SVD奇异值分解理论并用此理论对此方程进行了研究并计算得到了装置放电时刻。然后选取Marr小波用小波变换模极大值理论处理缓冲信号。对比分析了两者的结果,体现了SVD理论解决此问题的优越性。最后搭建实验平台用实验证明了此方法的有效性。
DCBM10A voltage buffer device provides continuous power within the stipulated time for subsequent load, it’s very important to accurately calculate discharge time. First, through theoretical deduction the capacitor discharge state equation is established. Then SVD singular value decomposition theory is introduced and the theory is used to analyze the equation, and discharge time is determined. And then Marr wavelet and wavelet transform modulus maximum theory are selected respectively to process buffer signal. The two results are analyzed and compared, which embodies SVD theory superiority. Finally experimental platform is built, which demonstrates the effectiveness of this method.
