Configurations

Macros
#define	PWM_FREQ_Hz   (CONTROL_FREQUENCY_Hz)
	PWM frequency in Hz.
#define	INVERTER_DEADTIME_ns   (200)
	Dead time (ns) value to be used.
#define	HAS_DUPLICATE_SWITCH   (PECONTROLLER_CONFIG == PLB_TNPC || PECONTROLLER_CONFIG == PLB_MMC ? 1 : 0)
	In inverters that have four legs per inverter that 4th leg will receive the same signal as the third leg, so they will both be interchangeable.
#define	RELAY_COUNT   (PECONTROLLER_CONFIG == PLB_TNPC || PECONTROLLER_CONFIG == PLB_MMC ? 0 : (PELAB_VERSION >= 4 ? 4 : 2))
	No of relays in the system.
#define	LEG_SWITCH_COUNT   (PECONTROLLER_CONFIG == PLB_TNPC ? 4 : 2)
	No of switches per leg.
#define	VFD_COUNT   (PECONTROLLER_CONFIG == PLB_6PH || PECONTROLLER_CONFIG == PEC_CUSTOM || PECONTROLLER_CONFIG == PLB_MMC ? 2 : 1)
	No of switches per leg.
#define	VFD1_PIN1   (1)
	1st pin of 1st VFD
#define	VFD2_PIN1   (VFD1_PIN1 + (HAS_DUPLICATE_SWITCH ? LEG_SWITCH_COUNT * 4 : LEG_SWITCH_COUNT * 3))
	1st pin of 2nd VFD
#define	DEFAULT_OUTPUT_FREQ   (25)
	The output frequency of the inverter 1st time the application is run. Current value can be updated from screen.
#define	DEFAULT_NOMINAL_FREQ   (50)
	The nominal frequency of the inverter 1st time the application is run. Current value can be updated from screen.
#define	DEFAULT_NOMINAL_m   (.7f)
	The nominal modulation index of the inverter 1st time the application is run. Current value can be updated from screen.
#define	DEFAULT_ACCELERATION   (1.0f)
	The default frequency acceleration.
#define	MIN_OUTPUT_FREQ   (1.f)
	The minimum allowed value of the output frequency.
#define	MIN_NOMINAL_FREQ   (1.f)
	The minimum allowed value of the nominal frequency.
#define	MIN_NOMINAL_m   (.05f)
	The minimum allowed value of the nominal modulation index.
#define	MIN_ACCELERATION   (0.1f)
	The minimum frequency acceleration.
#define	MAX_OUTPUT_FREQ   (100.f)
	The maximum allowed value of the output frequency.
#define	MAX_NOMINAL_FREQ   (100.f)
	The maximum allowed value of the nominal frequency.
#define	MAX_NOMINAL_m   (1.f)
	The maximum allowed value of the nominal modulation index.
#define	MAX_ACCELERATION   (1000.f)
	The maximum frequency acceleration.

Detailed Description

Use the configurations to control the PWM for the VFDs. Some control for the VFDs are provided on the external touch screen. While the limits and default values may be controlled from here. Make sure to set these values to proper limits to avoid generation of invalid output.

LEG_SWITCH_COUNT

#define LEG_SWITCH_COUNT   (PECONTROLLER_CONFIG == PLB_TNPC ? 4 : 2)

Note

This figure depends on the topology. e.g. TNPC requires four switches per leg

PWM_FREQ_Hz

#define PWM_FREQ_Hz   (CONTROL_FREQUENCY_Hz)

Note

Minimum value is 5000

VFD_COUNT

#define VFD_COUNT   (PECONTROLLER_CONFIG == PLB_6PH || PECONTROLLER_CONFIG == PEC_CUSTOM || PECONTROLLER_CONFIG == PLB_MMC ? 2 : 1)

Note

This figure depends on the topology. e.g. TNPC requires four switches per leg
