Single-phase thyristor rectifier

A block diagram and input parameters for a single phase thyristor rectifier are given in Table 1.

Single phase thyristor rectifiers		Control source (Digital inputs, Model) Digital input pins for: S1 (1..32) S2 (1..32) S3 (1..32) S4 (1..32) S1 logic (active high, active low) S2 logic (active high, active low) S3 logic (active high, active low) S4 logic (active high, active low) _control_property (all high, all low) Switching enabled Sen (digital input selection for PWM enable)) Sen_logic (active high, active low Weight = 2

A schematic block diagram of the single phase thyristor rectifier block is given in Figure 1 with corresponding thyristor arrangement and naming.

Digital inputs, when selected as a control input option, enables the user to assign gate drive inputs to any of the digital input pins (from 1 to 32/64). For example, if S1 is assigned to 1, the digital input pin 1 will be routed to the S1switch gate drive. In addition, theS1 logic, S2 logic, S3 logic, and S4 logic parameters select either active high(High-level input voltage VIHturns on the switch), or active low(Low-level input voltage VILturns on the switch) gate drive logic, depending on the user’s external controller design.

Digital Alias

If a converter is controlled by digital inputs, an alias for every digital input used by the converter will be created. Digital input aliases will be available under the Digital inputs list alongside existing Digital input signals. The alias will be shown as Converter_name.Switch_name, where Converter_name is name of the converter component and Switch_name is name of the controllable switch in the converter.
