The following examples demonstrate the diverse range of converter systems that you can build with SwitcherGear.
Each example indicates the typical items in the power converter that the controller must interface to. You can compare this against the hardware interface resources provided by SwitcherGear, listed in the table to the right.
|Gate Signals||12+ PWM outputs|
|Current & Voltage Sensors||16 ADC inputs with PWM-synchronous sampling|
|Other||Shaft encoderDigital I/O (24 VDC)Analogue I/O (±10 V, 4 to 20 mA, etc.)CAN, RS-232, RS-485, etc.|
Controller for a 3-phase induction motor using a 2-level IGBT voltage source inverter. Power derived from a simple diode rectifier.
Implement motor models, current controllers, PWM methods, field-weakening, sensorless control, etc.
Variations: DC link chopper, soft-charge for DC link capacitor, permanent magnet motor, etc.
Customisation: Add your code for flux model, field-oriented control, etc.
Controller for photovoltaic array using 1-switch boost converter. Or permanent-magnet synchronous generator (PMSG) using additional diode rectifier.
Use with single- or three-phase AC grid interface, or as part of a DC grid system.
Variations: Interleaved boost converter.
Customisation: Add your code for maximum power point tracking (MPPT).
Controller for 3-wire power quality applications such as STATCOM, harmonic filters, etc.
Variations: 4-wire, soft-charge for DC link capacitor.
Customisation: Add your code for grid support and harmonic filtering.
Controller for energy storage using buck-boost converter.
Variations: Buck or boost, interleaved converters, super capacitor, add network capabilities as part of a DC grid system.
Customisation: Add your code for battery management.
Controller for a 3-phase test motor using two 2-level IGBT voltage-source inverters and induction motor load. Power circulates through the DC link, so power rating of supply is minimised.
Ideal as a test platform for the development of motor models, current controllers, PWM methods, field-weakening, sensorless control, etc. Or use as a test bed for electrical machines.
Variations: soft-charge for DC link capacitor.
Customisation: Add your code for motor model, field-oriented control, etc.
