Files
file	pwrctrl_isr.c
	Contains Control loop interrupt Callback that acquires the ADC raw data and process it in the control loop, and use the control output for the PWM distribution for this converter.

Detailed Description

This document includes the interrupt function in power control.

Function Documentation

__attribute__()

void __attribute__

(

(__interrupt__, auto_psv)

)

Returns

void

This interrupt function is a ADC Core 0 interrupt executed every 100KHz This ADC is triggered using trigger b of PG1. This trigger is half of the phase difference between fixed and phase shifted leg

Definition at line 101 of file main.c.

Here is the call graph for this function:

ControlLoop_Interrupt_CallBack()

void ControlLoop_Interrupt_CallBack

(

void

)

Returns

void

This callback is executed every 100Khz. and is tied up to the ADC0 conversion ISR. The ADC0 itself is triggererd by half of the phase difference (half of the duty) between fixed and phase shifted legs

Here is the caller graph for this function:

PwrCtrl_ControlLoopExecute()

void PwrCtrl_ControlLoopExecute

(

void

)

Returns

void

This function is called to execute the control loop of the power converter. It comprise of Voltage Loop control (VLoop), Power Loop control (PLoop) and Current Loop Control (ILoop). Vloop and PLoop is ten times slower than the current loop with interleaved execution while Iloop is executed every time this function is called.

PwrCtrl_DroopAverage()

void PwrCtrl_DroopAverage

(

void

)

Returns

void

This function is called to keep and average of last 100 values needed in droop

Definition at line 138 of file pwrctrl_isr_extension.c.

Here is the caller graph for this function:

PwrCtrl_UpdateADConverterData()

void PwrCtrl_UpdateADConverterData

(

void

)

Returns

void

This function is called every 100KHz and triggers the ADC module. This also handles the updating of PSFB data members with its latest ADC raw values and collection of data for averaging.
