What is FPGA-based switching-controller for multilevel inverter (MLI) power semiconductors?

We employ an FPGA-based switching-controller to provide pulses for Multilevel Inverter (MLI) power semiconductors via their gate-drivers. The modulation strategies were implemented via an FPGA with a 32-bit floating-point architecture considering the IEEE-754 standard's recommendations. The portability of the design is ensured using VHDL .

Can an FPGA be used as a multichannel PWM signal generator?

Solutions similar to that of using an FPGA as a multichannel PWM signal generator are proposed in [17 - 19]. However, with the advancement in FPGA technology and the development of new tools and digital design techniques, there is a clear tendency to integrate complete designs in this type of device.

Can SPWM be integrated into a FPGA device?

As a low fraction (≈5%) of the FPGA resources is involved by the proposed SPWM generation scheme, additional inverter control algorithms (e.g., algorithms for controlling output voltage, current, power, etc.) can be integrated in the same FPGA device.

How do I convert a sine wave to a square wave?

There are a few different ways to approach your solution, but my recommendation would be to use an unbuffered inverter to convert your sine wave to a square wave, likely with a slow slew rate, and then send that signal into the SN74AUP1G14 to convert to a clean sine wave. The above is a simulated version of what I described.

How do FPGA pulse generation units work?

In the proposed FPGA design, the pulse generation section is sub-divided into two units in such a way that the digital values of the positive half-cycle of sinusoidal wave are counted in one unit and for the negative half-cycle are counted in the other unit.

What is an FPGA controller?

An FPGA controller is used to generate the requisite SPWM switching signals for the semiconductor switches, driven through the gate drivers.
