Dear Colleagues,
Power electronics digital control circuits are an important element
of modern electrical systems, with their applications ranging from
power stations, through electric cars to household electronics.
Modern control circuits are primarily digital, and their design
creates serious challenges that had never been encountered in their
analog counterparts.
The output current and voltage of these circuits is a result of the
overall circuit design; ensuring their high quality is critical for
many specialized applications, such as class-D audio power
amplifiers, active power filters or nuclear magnetic resonance
circuits (NMR).
The Special Issue on the topic of "Digital Signal Processing (DSP)
in Power Electronics Control Circuits" will focus on the problems
concerning design of effective control circuits.
Firstly, the inputs of digital circuits are typically composed of
analog signals, which represent circuit current and voltage. The
optimization of analog signal acquisition for digital circuits
necessitates a careful selection of the required sampling rate,
signal range, and the number of bits, as well as the implementation
of galvanic isolators, and anti-aliasing filters, considering their
combined effect on the signal-to-noise ratio (SNR), the bandwidth,
and jitter.
Another challenge is the design of the digital signal processing
circuit. A wide range of electronic components can be selected for
this application, including digital signal processors,
microcontrollers, and FPGAs. However, finding the appropriate device
for the right application has knock-on effects on the entire system.
Additionally, DSP algorithms play an important role, including the
choice of their arithmetic (fixed point vs. floating point).
Finally, in most cases, the modulator of the inverter represents the
bottleneck of the overall control circuit. Any advancements in this
area would enable an improvement in the overall design performance.
We would like to welcome submissions on the topic of "Digital Signal
Processing in Power Electronics Control Circuits", presenting novel
research concerning approaches to tackle any of the above problems.
The results can include analysis, design, simulations, and
implementation of the digital signal processing circuits for power
electronics.
