直接依据这些原理,因为尖锐的采样信号很难获得,因此,这两次滤波(Sa函数和理想低通)可以合并(级联),并且由于这各系统的滤波特性是物理不可实现的,所以在真实的系统中只能近似完成。
2. 模数转换器是将模拟信号转换成数字信号的系统,是一个滤波、采样保持和编码的过程。
模拟信号经带限滤波,采样保持电路,变为阶梯形状信号,然后通过编码器, 使得阶梯状信号中的各个电平变为二进制码。

电源由于功率大(达30kW),输出电压高(150kV),工作频率较高(20kHz),而对稳定精度、纹波及电压调节率均有较高的要求。选用先进的三相全控可控整流技术、大功率高频逆变器,用新型功率器件IGBT作为功率开关。三相全控可控整流和逆变器各自采用独立的控制板,IGBT驱动采用进口厚膜驱动电路,加上输入电网滤波器和平波电抗器及电容组成的滤波电路。使电源的功率变换部分具有较好的技术先进性和良好的功率变换性。
