The SynchronverterTM transforms renewable energy inverters into cutting-edge grid stabilizing devices. With the addition of the SynchronverterTM, inverters play an active role in the stabilization of grids whose considerable renewable energy source (RES) proportions would otherwise create significant instability.

By integrating with existing renewable energy inverters, the SynchronverterTM transforms them into a virtual synchronous generator device – without any inverter design changes. This is accomplished via an add-on control device that integrates with the inverter’s controller and utilizes a small, ultra-fast-response energy bank.


The SynchronverterTM enhances yields and maximizes the utilization of electricity provided by renewable energy sources in traditional and micro/smart grid topologies. The SynchronverterTM is IP protected, easy-to-implement and extremely well tested in diverse conditions.

The Synchronverter is a patented control algorithm that interacts with inverter switches and emulates the mechanical and electrical properties of a synchronous generator.

An algorithm for grid stability

  • The algorithm causes conventional AC/DC converters to mimic synchronous generators and create the inertia required for generating a stabilizing effect.


  • The SynchronverterTM mimics local control loops similar to synchronous generators' classical control, generating the active participation of power sources in grid stabilization. This is accomplished in harmony with other generators on the grid.


  • The control algorithm computes the induced voltages on the virtual generator's stator winding (from the currents, angular position and angular velocity) at any given moment, without lags or tracking errors.


  • Droop coefficients and complex non-linear droop curves can be easily imposed via the control processor software. They can also be programmed to depend on demands sent from the grid operator.

How does the SynchronverterTM work?

   The Synchronverter's unique technology performs:

  1. ​Stabilization: The grid’s instantaneous reaction (frequency regulation) capabilities are greatly enhanced.

  2. Spinning Reserve: The grid is able to mitigate generation loss or an increase in load.

  3. Voltage Control: The grid can support power quality and accommodate changes to system voltage levels (reactive power regulation).

  4. Standalone: Grids work effectively in "island" mode (lack of grid referencing).

  5. Smoothing: Production management of flexible and non-dispatchable load (capacity firming).
