Within the scheme, phase currents are reconstructed using knowledge of the DC-link current and switching states. The generation of switching signals is based upon traditional delta-hysteresis regulation (DHR). However, modifications are made to DHR to ensure the DC-link current always contains sufficient information to reconstruct phase currents. Experimental results obtained from a vector-controlled induction machine are used to show that there is a relatively small difference between the performance of the DHR and DDHR schemes.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

With conventional controls, however, this sharing is unstable. Recent literature work proposes complicated feedback loops to correct the problem, at the cost of dynamic performance. This paper shows that a simple sensorless current mode control stabilizes sharing with fast dynamics suitable for advanced digital loads. With this control in place, a \"super-matched\" current sharing control emerges. Sharing occurs through transients, limited only by the energy limits of the converters. The control approach has considerable promise for high-performance voltage regulator modules. For even faster response, clamping techniques are proposed.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.

The motivation is because the control function mappings from the desired waveform's two modulation indices to its step-angles are not simple closed-form expressions, so using look-up tables to implement the mappings accurately and comprehensively would require a significant amount of memory. The neural network was first trained using a single central processing unit, and the results were then compared to similar training using distributed computing (with multiple local area network-connected central processing units). It was found that using distributed computing reduced significantly the training time needed to achieve the desired level of accuracy.","PeriodicalId":137483,"journal":{"name":"2004 IEEE Workshop on Computers in Power Electronics, 2004.
