Detailed Description

User-declaration of phase current feedback parameters of the buck converter using physical quantities.

Macro Definition Documentation

◆ BUCK_ISNS_ADC_TRG_DELAY

#define BUCK_ISNS_ADC_TRG_DELAY (float) 80.0e-9

ADC trigger delay for current sense in [sec].

Definition at line 659 of file dpsk3_hwdescr.h.

◆ BUCK_ISNS_AMP

#define BUCK_ISNS_AMP 1

Use shunt amplifier as main current feedback source.

Definition at line 647 of file dpsk3_hwdescr.h.

◆ BUCK_ISNS_CT

#define BUCK_ISNS_CT 0

Declaration of phase-current feedback properties.

In this section the phase-current feedback signal scaling, gain, valid signal limits and nominal operating point is specified. Physical quantities are used to define parameter values to ease the system configuration.

As DPSK3 supports two different current sense devices (current sense transformers and shunt amplifier devices) users can select which one should be used for regulating the output current. Based on the selection made, the appropriate feedback channels and signal scaling values will be used by the firmware.

Macros are used to convert given physical values into binary (integer) number to be written into SFRs and variables and being used in runtime calculations.
(see Buck Converter for details) Use current sense transformer as main current feedback source
