IP cores

Power Smart Control provides IP Cores for the Digital Control of Power Electronics. Control structures and function blocks for SoC and FPGA based controllers:

PI, PID, PR
DQ structures, alpha-beta structures
PLL and sequence separators
Feedforward compensations
Sampling techniques
Optimized SHE (scalar or vector control)
Space vector modulation
Overmodulation techniques, etc.
Others
Optimized SHE modulator for vector control, implemented as an IP core in an SoC-FPGA

Advanced control algorithms.
Example of IP Core: Optimized SHE modulator for vector control

PLL, gate signal, line voltage and filtered line voltage in response to amplitude, frequency and phase steps

Control boards

Digital Control improves performance, but it can be a real challenge if you don’t master the technology:

  • New control algorithms & optimized modulators
  • New digital platforms
  • New design tools and methodology

We have designed a Universal Control Board including up to 12 PWM signals, with integrated current and voltage sensors, Power Supply, and communication protocols (Ethernet, CAN, USB 2.0).

Do you need any modification? It is completely customizable, and we will do it for you.

Applications:

Wind Turbine Back-to-Back Converter
Photovoltaic Inverters (2 inverters in parallel)
Railway Inverters (2 inverters in parallel)
High power DC-DC multi-phase (3Ph interleaving Buck-Boost Converter)

Test benches

Considering the complexity of the control boards of current power electronics systems used in Energy, E-mobility or Aerospace applications it is necessary to validate properly these control systems before they are installed onsite or simply tested with the real systems.

Our automatic Test Bench tailor-made designs perform a completely automatic verification of customer control units helping the manufacturer to deliver a 100% functional control unit: zero errors, maximum quality.
