These notes present solutions for the implementation of control software, with practical, imperix-related aspects in mind. They mostly focus on one specific subsystem and may link to other technical notes if needed. Technical notes are application-independent.
This technical note addresses the sensorless control of motor drives using a back-EMF sliding-mode observer. The technique allows speed and position estimation of a Permanent…
This note covers the I-f startup method for speed sensorless motor control and its implementation on a programmable power converter prototype.
This note covers the V/f control of an induction machine and its implementation on a programmable drive inverter.
This note introduces a conventional control for Modular Multilevel Converters (MMC). The converter is used in a DC/AC inverter configuration and is connected to the three phase grid.
This example generates three phase alternating currents from a voltage source inverter in an open loop manner. It can be used in a grid-forming application.
In voltage source converters, pre-charging the inverter DC bus is required before connecting it to external voltage sources, so that to avoid inrush currents that may be destructive.
Fictive axis emulation is a vector control technique that is mostly used in single-phase inverter applications, where the second axis β of a rotating reference…
Power electronic converters generate non-ideal current and voltage waveforms, which unavoidably include a broad spectrum of undesirable switching harmonics. In most applications, these harmonics must…
Some power sources, like solar panels, present power characteristics that strongly depend on the operating conditions. In such cases, Maximum Power Point Tracking (MPPT) is often applied to maximize the extracted power.
This note presents several modulation techniques to operate a Dual Active Bridge (DAB) converter. First, the topology and the theoretical aspects of the Dual Active…
