 The initial screen of the simulation environment flowSIM.exe can bee seen on the above picture (one power module
 already selected).

 上面的图片是flowSIM.exe仿真环境的最初显示屏幕。(已选择一种模块)

 1. Module Family Browser模块系列浏览器

 for the selection of the module to be simulated. The list is generated based on the Datas.dat file (update if new data
 are available)

 用以选择要仿真的模块,此列表是根据Datas.dat 文件生成的(有新资料时请更新)。

 2. Description of the Module Topology模块布局描述

  the modules are divided in six functional blocks: rectifier, PFC shunt, PFC, brake, inverter shunt, and inverter. This
  is a maximum configuration. If a certain function block is included in the module under simulation (MUS) then the
  module Tyco part number will appear above the function block. The functional blocks that are not available will get
  a red border. The topology of the MUS can by changed clicking on the schematic, in this way the available power
  modules can be combined. With right click on the schematic the module selector browser will pop up with the list
  of those modules which contains the selected functional block. With the left click the selected functional block
  configuration can be changed.

 模块分成六个功能块:整流器,PFC分路,PFC,刹车,逆变器分路,逆变器。这是最大程度的构造。如果仿真的模块包
 含某一功能块那么TYCO的型号会出现在该功能块上方;模块没有的功能块则带有红色的边框。不同地单击示意图可改
 变仿真模块的布局,从而和其他模块结合起来。右击示意图,会跳出模块选择浏览器(列出具有选中的功能块的模
 块),左击则可以改变选中的功能块结构。

 3. Component Selector元件选择器

 for the selection of the component to be simulated. Components which were added to the basic topology also will
 appear in the list. Different blocks from different modules can be simulated.

 用以选择要仿真的元件,添加到基本布局的元件也会出现在列表里。可以仿真不同模块的不同功能块。

 4. Input Parameters输入参数

 can be three phase input or single phase , for three phase input the input voltage will be considered line to line
 RMS ,for single phase line to ground RMS. If the MUS have three phase input and a PFC stage is added in this
 case the input will be changed to single phase. If the MUS has no rectifier by default the input will be considered
 three phase, but of course can be switched to single phase.

 可以是三相输入或单相。如果是三相输入,输入电压视为线至线均方根,单相则视为线至地均方根。如果仿真模块带有
 三相输入且加上PFC分级, 那么输入会变成单相。如果仿真模块默认没有整流器,输入会被当成是三相,但当然可以变
 成单相。

 5. PFC and DC link Parameters功率因数修正和DC连接参数

 Udc and fPFC is active if a PFC stage was selected. The AC ripple present on DC link voltage depends on the value
 of the DC link capacitor C.

 如果选择了PFC分级那么Udc 和 fPFC是活跃的. 在DC连接电压出现的AC波纹取决于DC连接电容器C的值。

 Udc is the output voltage of the PFC
 Udc是PFC的输出电压

 fPFC is the switching frequency of the PFC stage.
 fPFC是PFC分级的开关频率。

 For the simulation of the PFC stage there is the possibility to add a six pack which will serve as a load for the PFC
 even if in the module does not included a six pack. (Although the six pack is a virtual one the output parameters field
 is active)

 进行PFC分级仿真时,即使模块不含有6 封装,也可以添加一个作为PFC的负载。(虽然此6 封装是虚拟的但输出参数域
 却是活跃的。)

 in case of a PFC simulation the Udc must be higher than peak of Uin.

 进行PFC仿真时,Udc 需大于Uin的峰值

 6. Output Parameters of the Six Pack6封装的输出参数

 In this field can be introduced:这里主要介绍:

 the output voltage line to line RMS (first harmonic of the output voltage under nominal operating conditions)

 输出电压线至线均方根(标称工作条件下输出电压的第一谐波)

 the output current RMS

 输出电流均方根

 cos (fi)- cosine of phase delay between first harmonic of output voltage and current, in the range of -1 to 1. For
 positive values there is the motoring mode for negative values there is the generator mode. In generator mode the
 calculations are made considering the Dc link voltage equal to brake voltage.

 cos (fi)-输出电压第一谐波和电流之间相位延迟的余弦值,介于-1至1。正值是电动机模式,负值则是发电机模式。发
 电机模式的计算将DC连接电压视为等于刹车电压。

 Ubr(brake voltage). Ubr must be fixed to a higher value than the rectified peak of Uin (Uin pk-pk )

 Ubr(刹车电压)。Ubr的值必须设置得比整流的Uin (Uin pk-pk )的峰值高。

 fsw PWM clock frequency, is necessary to calculate switching losses. Please note that fsw is given in [Hz].

 fsw PWM时钟脉冲频率,用以计算开关损耗。Fsw的单位是[Hz]。

 Output frequency-the first harmonic output voltage frequency, (can be selected from a list)

 输出频率-输出电压第一谐波频率。(可从列表中选择)

 PWM method-can be normal or 3rd harmonic (the 3rd harmonic was added to the first harmonic of the modulator
 signal)

 PWM方法-可以是标准的或第三谐波(第三谐波已被添加到调节器信号的第一谐波)

 7. Gate Settings门极参数设置

 you can specify the gate resistances of inverter and PFC switch (any positive value is accepted). By default Rg on
 and off are the nominal recommended values. The voltage level for the gate driver can be symmetrical +/- or
 positive to zero and is fixed (can not be modified)

 可以设定逆变器和PFC开关的门极电阻(任一正值均可)。

 开通和关断的Rg值均默认为标称推荐值。门极驱动的电压电平可以是对称的+/-或正数至零,但是是固定的(不可以改
 变)。

 8. Input and Output circuit Waveform Graphs输入和输出电路波形曲线图

 can be used for the visualization of the detailed circuit simulation results such as input , output, and component
 current and voltage .

 显示详细的电路仿真结果,例如:输入、输出、元件电流和电压。

 9. Static and Switching Characteristics静态和开关特性

 under this menu are the static and switching characteristics used for the power loss calculations. The static loss
 for each device is computed based on the output characteristics. U= f(I) The output characteristic was measured at
 25
and for 125. For any other temperature the linear interpolation method was used to calculate the voltage
 drop on device.

 显示静态和开关特性,用以计算功率损耗。

 每一器件的静态损耗计算以输出特性为基础。U= f(I) 输出特性是在25 0C和 125 0C下测量的。至于其他温度下,则用
 线性插值法计算器件的压降。

 To be able to calculate the switching loss were measured Eon , Eoff and Erec These energies are a function
 of Rg ,Ic ant T. E=f(T,Ic,Rg).This function was made continuous using the interpolation method.(Measurements
 were taken at 250C and 1250C and discrete values of Ic and Rg)

 为了能够计算,开关损耗测量了Eon , Eoff 和 Erec。这些能量组成Rg ,Ic 和 T的函数,E=f(T,Ic,Rg). 此函数也是
 用线性插值法得出。(在250C和1250C下,采用Ic 和 Rg的不连续值测量的)

 For thermal modeling first has to be fixed the heat sink temperature (Tsink=800 C is the default value in the
 simulation software). The calculated total power loss is applied to a serial R-C thermal model for defining the chip
 temperature. Graphical representation of Rth and Tau can be seen.

 至于热量模仿,首先要设定散热器的温度(此软件的默认值是Tsink=800 C)。计算出的总功率损耗接到一个串联
 的R-C热量模型以决定芯片的温度。Rth 和 Tau均以曲线图显示。

 10. Loss and Temperature Graphs损耗和温度曲线图

 losses and chip temperature.
