#define	PWM_CLOCK_PERIOD   (float)(1.0 / PWM_CLOCK_FREQUENCY)
	Conversion macros for user-declarations of PWM parameters.
#define	MAX_SWITCHING_PERIOD   (float)(1.0/MINIMUM_SWITCHING_FREQUENCY)
	Switching period in [sec].
#define	MIN_SWITCHING_PERIOD   (float)(1.0/MAXIMUM_SWITCHING_FREQUENCY)
	Switching period in [sec].
#define	MAX_PWM_PERIOD   (uint16_t)(float)(MAX_SWITCHING_PERIOD / PWM_CLOCK_PERIOD)
	This sets the switching period of the converter.
#define	MIN_PWM_PERIOD   (uint16_t)(float)(MIN_SWITCHING_PERIOD / PWM_CLOCK_PERIOD)
	This sets the switching period of the converter.
#define	PERIOD_RANGE   (uint16_t)(MAX_PWM_PERIOD - MIN_PWM_PERIOD)
	This is the calculation of Period range. NOTE: only use in Debugging moode using digital power development board.
#define	ADC_PERIOD_RANGE   (uint16_t)(float)(PERIOD_RANGE / ADC_RESOLUTION)
	This is the calculation for ADC equivalent with Period range. NOTE: only use in Debugging moode using digital power development board.

Detailed Description

These conversion macros are used to convert user settings defined as physical quantities into binary (integer) numbers, which will be written to registers and variables and used in calculations throughout the firmware.
