In this paper, a special control solution called virtual voltage source (VVS) is developed for no-load tests of induction machines. This concept is applied to a 2 × 27 MVA high-power machine test bench where the test bench is requested to precisely

Shipboard power system is moving towards more insertion of medium voltage (MV) dc sub-system in the existing MVAC power system. Isolated bidirectional dc-dc converter, analogous to a dc energy router, is one of the key enabling components in such a M

Power capability is one of the most important criteria for converters in high-power applications. The normal approach for converters increasing the power capability is to use devices with larger Safety Operating Area (SOA). In this paper, a novel con

The matrix converter is a single-stage ac-ac power conversion device without dc-link energy storage elements. Any disturbance in the input voltages will be immediately reflected to the output voltages. In this paper, a modified space vector modulatio

A novel voltage-based commutation (VBC) strategy without explicit input-voltage measurement is proposed in this paper. By properly selecting the width of the critical intervals, the two-step uncritical commutation and four-step critical commutation a

A nonlinear compensation method for matrix converter is proposed to compensate the voltage error between the reference voltage and actual output voltage. The output voltage error caused by voltage-based commutation process is analyzed, and the parasi

In this paper, control strategies of a 22 MW / 27 MVA machine test bench using pumpback topology are introduced. The current loop design at extremely low pulse ratios (e.g. 600 Hz carrier frequency / 80 Hz load frequency) is developed. The system sta

The position sensorless vector control scheme for the brushless excited synchronous motor based on the IGCT converter is presented in this paper. Since the instantaneous excitation current cannot be directly measured in this application, an adaptive

For high-power converters with low pulse ratios (e.g. 80 Hz load frequency with 600Hz carrier frequency for a 27 MVA Variable Frequency Drive), the current control loop design has been a challenge due to the large signal delay and potentially higher-
