  • Boost_Converter
    说明:  升压转换器是一种DC / DC电源转换器,可将电压从其输入(源)升至其输出(负载)。在连续导通模式下(流经电感的电流永远不会降为零),升压转换器的理论传递函数为: 占空比在哪里0.5 在此示例中,转换器从250 V电源馈送RC负载,并且PWM频率设置为31 kHz。 模拟 运行仿真并观察示波器上的波形。确认负载电压(Vout)的平均值非常接近理论值:Vout = 250 /(1- 0.5)= 500V。(A boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is: where is the duty cycle.0.5 In this example, the converter is feeding an RC load from a 250 V source and the PWM frequency is set to 31 kHz. Simulation Run the simulation and observe waveforms on Scope. Verify that the mean value of the load voltage (Vout) is very close to the theoretical value of: Vout = 250 / (1 - 0.5) = 500 V.)

  • ulawcompander.m
    Companding is essentially a technique for achieving non-uniform quantization. There are basically 2 methods which are most popular in literature.:-A-law companding and u-law companding. These algorithms help in achieving to an extend, compression. The given code shows how to compress a 14-bit code to 8-bit code and its digital implementation using matlab. Please contact by mail if a detailed description of code is needed.
