Motor Drive Emulators are regenerative power supplies designed to emulate a powertrain system.
They emulates the behaviour of an inverter and electrical motor working together.
The user can configure the MDE with different profiles of velocity, acceleration and breaking.
Apart from that, other parameters can be configured, as motor and inverter power, switching frequency of
inverter and some faults too.
The DC input of MDE can be configured with 3 independent channels to test different storage systems
at the same time or they can be parallelized for high current applications in 1 single-channel.
This equipment has energy recovery capability which allows saving energy during the working period
by returning the energy to the power grid (saves up to 92%).
The converter is formed by an Active Front End, a DC bus stage, and DC/DC converter with output filters and sensors.
The following operating modes can be selected by the user:
- Current Mode (CM): the output AC current is controlled by the value selected by the user
- Voltage Mode (VM): the output AC voltage is controlled by the value selected by the user
- Power Mode (PM): the output AC power is controlled by the value selected by the user
- Vehicle profile
Regenerative power supply
The converter is based on a hardware topology allowing a bidirectional power flow from the DC input
to the grid output providing important energy savings.
