你好 我是用TI 的HV_SOLAR_DC_AC_v1.1的软件及他的开发版solar inverter HV DC-AC board V2.2，在off-grid情况下，我将main.c中程序代码第867行的 PWMDRV_Duty=&dwInv_Voltage打开(将 // 消去)和setting.h中的incr_build改为1，照着Quick Start Guide for Solar HV DC-AC Board_Rev1.3进行测试，但输出端电流和电压直接为0，GUI却显示Normal Inverter Mode，若没有修改main.c中的程序代码，GUI则显示DCBUS Voltage Under，请问是出了甚么问题?
注：我没有DC-DC模块，只有DC-AC模块
Kurt,
下面是我以前做的一些测试步骤，你可以参考一下，应该是某些开关没打开。
Test Procedure
(1) Before the test, please make sure the unit test is complete.
(2)Make sure the firmware in the control card is no voltage loop and no PLL version.
(3) Insert the +15V power adapter to the J1, then switch on the S1.
(4) Check if the LD2 of the control card is flashing per 1 second.
(5) Power up the DC source, set up the current limitation to 2A, then enable the output, then regulate the output voltage of the DC source to 400V slowly. Measure the voltage between the +BUS and –BUS, check if the voltage is equal to the DC source voltage.
(6) Press the SW1 for over 1s to turn on the board, to see if the LD2 of the control card is constantly lightened. If yes, do the following test.
Set the INCR_BUILD=1 in the SolarHv_DCAC-Setting.h file, and then rebuild and load the project.
Do not connect any load to the output of the DC-AC board.
Connect the GUI to the board, and check the status of the DC-AC board.
Picture 1 and Picture 2 is the test result of the board when the DC voltage is set to 100V.
In the Picture 1, we can check the status of the DC-AC board form the GUI.
Picture 2 is the output AC voltage waveform from the.
