1.1 Open-loop Voltage control : Phase A 6 / 13

1.1 Open-loop Voltage control : Phase A 7 / 13

1.1 Open-loop Voltage control : Phase B 8 / 13 Testing of the fixed point controller - AC motor module: PM machine - Three Sliders, which set the reference amplitude and frequency values - A simplified converter model using three ± 12[V] limiters (we use a 24[V]DC bus) Use of controller dialog box : operational variables Phase A

1.1 Open-loop Voltage control : Phase B 9 / 13

1.1 Open-loop Voltage control : Phase C 10 / 13 모 터와 EVM board 연결 - 전원연결포트 부터 검은색, 빨간 색, 흰색 순으로 연결 - J4 encoder 연결 EVM board 와 컴퓨터 연결 - Control card 와 컴퓨터는 USB 를 통해 연결 ( 전원 쪽 이용 ) 실험 kit setting

1.1 Open-loop Voltage control : Phase C 11 / 13 ‘ Controller' module: this contains all the elements for drive control. This module is used to compile a out file using Code Composer Studio (CCS 5). Inputs to controller module : normalized reference frequency and amplitudes conv 'on/off' button: activates converter 'channel ‘ button: selects diagnostic channels to be viewed: ch4/ch3 or ch2/ch1 Outputs: LED markers - show which two diagnostic channels('red' means selected ) Per unit, measured DC bus voltage

1.1 Open-loop Voltage control : Phase C 12 / 13 Open loop voltage controller Operation variables. Main motor control unit. 100Hz unit: controls LEDS which show that MCU is operating and all background tasks. Diagnostic tool unit: used to look at 4 'test' signals real time Main motor control Voltage controller. ADC-PWM unit: controls the three half bridges of the converter and measures the voltages from the shunt resistors, conv. phases and DC bus Current trip unit: provides software based overcurrent protection

1.1 Open-loop Voltage control : Phase C+ 13 / 13 We need a ‘ -d ’ version of the previous simulation that can run the ‘ xxx.out ’ file.
