Feed converter¶

Deutsch | English

• Power flow: bidirectional
• Maximum power: 90 kVA
• Connected to: TUB network, Lab AC + DC network

AC/DC to DC/AC and to DC/DC converter with constant voltage DC link (grid-shaping)

TUB network: 3-phase distribution, 400V
Lab AC network: 3-phase with neutral line, maximum 400V / 160A, frequency variable (0.1 to 400 Hz)
Lab DC network: 3 lines (+, +, –), maximum 300V / 350A

• Fig. 1: Feed converter

The control model (Matlab/Simulink) for converter operation (IGBTs) is loaded into the real-time environment (target)

Measured values of I and V are feed- backed to the control program (HiL)

The lab faced converters form the lab networks (AC or DC) according to predefined parameters

The TUB network faced converter retains the DC link at constant voltage
