Digital closed loop control and diagnostic functions

implemented

250WControl.c:

This is the main file of the microinverter. It includes the firmware-code for the closed and

open loop control, the input and output protection and the LCD display management. The

first function, called InitControl(), contains the init data for the DC-DC and DC-AC section. In

particular, the DC-DC information is contained in the InitStructure, the DC-AC are contained

in the DCAC_InitStructure and the data sensing part in the DS_ InitStructure.

void InitControl(ControlMode_t mode)

{

GPIO_InitTypeDef GPIO_InitStructure;

DCDC_TypeDef_t InitStructure;

DCAC_TypeDef_t DCAC_InitStructure;

DS_TypeDef_t DS_InitStructure;

/*DCDC Converter configuration */

InitStructure.Counter = DCDC_COUNTER;

InitStructure.DutyCycle = DCDC_DUTYCYCLE;

InitStructure.frequency = DCDC_FREQUENCY;

DCDC_Init(&InitStructure);

/*DCAC Inverter init configuration*/

DCAC_InitStructure.Counter = DCAC_COUNTER;

DCAC_InitStructure.DeadTime = DCAC_DEADTIME;

DCAC_Init(&DCAC_InitStructure);

ControlMode = mode;

/*DataSensing Init configuration*/

DS_InitStructure.Counter = DCAC_COUNTER; //--the same counter of the

DCAC

DS_InitStructure.DataRegister =

(vu32 *)&DataSensingIO;

DS_InitStructure.RegisterSize = DATA_SENSING_SIZE;

if (mode == ClosedLoop)

DS_InitStructure.OnAcquisition = ExecControl;

else

DS_InitStructure.OnAcquisition = ExecControlOpenLoop;

DS_Init(&DS_InitStructure);

/*Calibration of data sensing ***AFTER DS_Init*** */
