This page presents a method for selecting an inductance value for a Dual Active Bridge (DAB) isolated DC-DC converter. DAB converters can be easily constructed…
This technical note provides an introduction to the LLC converter, which is an isolated DC-DC converter, popular in a multitude of fields.
The fundamental harmonic approximation is presented as a modeling technique before the operation of the LLC converter is discussed above resonance, at resonance, and below resonance.
Following that, this technical note demonstrates how to build and operate an LLC converter using imperix hardware and software, and compares the physical implementation with the theory and the simulated plant.
Unlike continuous PWM, where the pulse width is modulated throughout the entire switching cycle, Discontinuous PWM introduces breaks or gaps in the modulation process. These…
This technical note presents a conventional PI controller-based current control strategy, using a buck converter as example. The developed example may be employed as an…
This technical note addresses possible implementations for a discrete PI controller and provides general insight into PI tuning strategies. It also includes practical implementations for…
This page explains how to get started with the motor drive bundle and the motor testbench. It provides a comprehensive overview of the hardware configuration…
The DQ-type PLL is a basic Phase-Locked Loop (PLL) used to extract the phase information of three-phase voltages. It operates by minimizing the voltage projected…
This page presents an implementation example of Selective Harmonic Elimination (SHE) using the PP-PWM modulator. This example addresses a high-power 3-level NPC inverter tied to…
The FPGA-based PP-PWM (programmed pulse pattern) peripheral provides a specialized PWM scheme for two and three-level inverters, which relies on pre-computed pulse patterns. This type…
This page covers a possible control algorithm for controlling the secondary DC voltage of a DAB converter. A working prototype is built using PEH full-bridge…
