3-Phase Inverter Model VI

Owning Palette: Inverter VIs

Requires: Electric Motor Simulation Toolkit

Simulates a three-phase inverter. You must manually select the polymorphic instance you want to use.

3-Phase Inverter Model (Ideal)

Simulates an ideal three-phase inverter.

	current specifies the three-phase current, in amperes, of the motor in the last simulation cycle. The current represents the three-phase current in a three-phase electric power system. Therefore, this array must have three elements, and each array element must specify one phase of the current.
	gate signal specifies the control signal from the controller and PWM modulation. The gate signal represents control command for the six switches within the inverter. Therefore, this array must have six elements.
	DC voltage specifies the DC voltage, in volts, on the inverter.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	voltage returns the three-phase voltage, in volts, of the electric motor. The voltage represents the three-phase voltage in a three-phase electric power system. Therefore, this array must have three elements, and each array element must specify one phase of the voltage.
	error out contains error information. This output provides standard error out functionality.

3-Phase Inverter Model (Advanced)

Simulates an advanced three-phase inverter.

	current specifies the three-phase current, in amperes, of the motor in the last simulation cycle. The current represents the three-phase current in a three-phase electric power system. Therefore, this array must have three elements, and each array element must specify one phase of the current.
	gate signal specifies the control signal from the controller and PWM modulation. The gate signal represents control command for the six switches within the inverter. Therefore, this array must have six elements.
	DC voltage specifies the DC voltage, in volts, on the inverter.
	inverter parameters specifies the characteristics of the inverter. IGBT forward voltage drop specifies the forward voltage drop, in volts, of the insulated gate bipolar transistor (IGBT) in the inverter. The value of IGBT forward voltage drop must be equal to or greater than 0. The default is 0. diode forward voltage drop specifies the forward voltage drop, in volts, of the diode in the inverter. The value of diode forward voltage drop must be equal to or greater than 0. The default is 0. conductance specifies the conductance, in siemens, of the switches in the inverter. The value of conductance must be greater than 0. The default is 1.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	inverter fault specifies the fault of the inverter. fault type specifies the type of the fault. 0 No Fault (default)—No fault occurs. 1 IGBT Open Fault—Any IGBT is interrupted. 2 Diode Open Fault—Any diode is interrupted. 3 IGBT and Diode Open Fault—Any IGBT with diode is interrupted. 4 IGBT or Diode Short Fault—Any IGBT or diode is bypassed. fault switch index specifies the index of the switch which is in fault state. 0 Phase A Upper Switch (default) 1 Phase A Lower Switch 2 Phase B Upper Switch 3 Phase B Lower Switch 4 Phase C Upper Switch 5 Phase C Lower Switch
	voltage returns the three-phase voltage, in volts, of the electric motor. The voltage represents the three-phase voltage in a three-phase electric power system. Therefore, this array must have three elements, and each array element must specify one phase of the voltage.
	error out contains error information. This output provides standard error out functionality.
