Active Front End (AFE)
This technical note introduces the working principle of an Active Front End (AFE) and presents an implementation example built with the TPI programmable inverter.
11-kW, Bidirectional Three-Phase Three-Level (T-type)
This reference design provides an overview on how to implement a bidirectional three-level, three-phase, SiC-based active front end (AFE) inverter and power factor correction (PFC) stage.
Basic principles of regenerative drive operation
In this post we offer an introductory overview of regenerative drive operation (also referred to as “Active Front End” or “AFE”), covering the basic principles and requirements. Basic AC drives are not regenerative,
Understanding inverter voltage
The start inverter voltage is the minimum input voltage required for the inverter to initiate the conversion process. In the case of a 12V inverter, the start inverter voltage is
Inverter Specifications and Data Sheet
Most VFDs produce an output voltage that is equal to the motor nameplate voltage while operating at full speed. Motors require full voltage to achieve rated torque at full speed at rated
Active front ends – Automatic Control Laboratory | ETH Zurich
Our research mostly focuses on addressing these challenges for grid inverters with LCL filters using model predictive control (MPC) with hybrid or linear models.
Products
The Active Front End (AFE) is a controllable rectifier with advantages such as providing bidirectional power exchange between AC and DC power and regenerating reusable power to the mains to reduce the cost of power.
Inverter front-stage frequency and output voltage regulation
We consider a data-driven frequency and voltage regulator for inverter-based power systems, specifically those integrating energy storage systems (ESSs) and photovoltaic (PV) arrays.
The Benefits of an Active Front End (AFE) Drive
An Active Front End (AFE) or Regen Inverter not only reduces harmonics, but also provides other benefits that can reduce costs. Rather than using diodes in the rectifier to convert the incoming AC power to DC,
