SV-PWM – Space vector PWM
The SV-PWM block generates PWM signals based on the Space Vector Modulation (SVM) algorithm. This algorithm determines the three vectors that are the closest to…
-
SB-PWM – Sandbox PWM
The FPGA sandbox PWM block allows driving the PWM output from a user-made modulator from within the FPGA. Information on FPGA edition is available on Editing…
-
DO-PWM – Direct output PWM
The Direct output PWM block sets PWM output(s) directly to ‘0’ or ‘1’. This technique is typically used for Model Predictive Control (TN162) or Direct…

CB-PWM – Carrier-based PWM
The Carrier-based PWM block generates PWM signals based on one of the 4 carrier shape illustrated below: triangle, sawtooth, inverted triangle, inverted sawtooth. When using…

PWM – Pulse Width Modulators
The Pulse Width Modulators (PWM) share the dead-time generation and the activate/deactivate features, configured through the output mode, deadtime, and activate parameters. The said PWM…

DEC – Angle decoder input
The angle decoder (DEC) block decodes quadrature-encoded signals produced by incremental encoders for motor drive applications. The imperix controllers provide decoder inputs for quadrature-encoder speed/position…

CLK – Clock generators
Imperix controllers feature 4 clock generators, CLK0, CLK1, CLK2 and CLK3, running at 250 MHz. They provide time bases for FPGA resources such as the…

CONFIG – Control task configuration
SD001
The CONFIG block primarily serves to configure the main clock (CLK0) as well as its derivatives. Together, these clocks define the frequency and phase of…
