They can be directly connected to high voltages and the multilevel voltage synthesis reduces the harmonic distortion introduced. Current clamp is a term that describes the current staying at zero for extended periods of time upon current direction reversal in a inverter driven load. A control requirement of these converters is to maintain voltage balance between all capacitors in the converter. The brushless doubly fed reluctance machine (BDFRM) is a new machine design with potential applications in turbo-machinery, variable speed constant frequency (VSCF) hydro and wind power applications, commercial and industrial heating, ventilation and air conditioning (HVAC) applications, and pump applications. © 2006 IEEE. Current clamp is the term used to describe the phenomena of inverter controlled current staying at zero when the current crosses from positive to negative. Mitt namn är Robert Loforsen. This is mainly due to the fact that reluctance rotor designs were not capable of generating saliency ratios large enough to make the BDFRM competitive with other machines.

It is caused by the dead-time in the inverter that is required to prevent current shoot-through. The structure and control of the system is presented, which shows that the DC link voltages can be individually controlled according to MPPT demands, negating the need for DC/DC converters. 16 records for Betz Robert.

In addition, they have individual DC links ideal for connecting photovoltaic arrays. Computer simulation results are then presented to confirm the control scheme operation. The control has been studied previously in several papers however the electromagnet design of this machine is now being studied with the key issue being whether to use an axially-laminated rotor or a radially-laminated rotor. The converter consists of a number of cascaded half bridge cells with isolated capacitors to make up an upper and lower arm in each phase. This is discussed in the paper.

The paper shows the impact of the interaction of the primary and secondary windings harmonic on the possible performance of the machine. Direct-current motors are extensively used in variable-speed drives and position-control systems where good dynamic response and steady-state performance are required. Das Online-Seminar mit Robert Betz live in Deinem Wohnzimmer mit ca. Simulation and experimental results are presented to validate the investigation. The widespread proliferation of power electronics and ancillary control circuits into motor control systems in the past two or three decades have led to a situation where motor drives, which process about two-thirds of the world's electrical power into mechanical power, are on the threshold of processing all of this power via power electronics. The load may be a conveyor system, a traction system, the rolls of a mill drive, the cutting tool of a numerically controlled machine tool, the compressor of an air conditioner, a ship propulsion system, a control valve for a boiler, a robotic arm, and so on. This, together with the promise of higher efficiency and simpler control compared to the BDFIM, means that further investigation of the BDFRM is warranted. © 2015 IEEE.

Our work has been primarily motivated by problems arising from the control of variable speed ac and dc machine drives. A new control scheme based upon input areas has been devised to enable successful operation under such circumstances. In addition, they have individual DC links ideal for connecting photovoltaic arrays. We discuss these issues and present an adaptive controller based on derivative feed-forward control and the MIT-Rule that has performed well when applied to the tracking antenna problem. This paper considers a 19 level three-phase CHB converter photovoltaic power system without sensing the photovoltaic array current for MPPT. A device that can present the dynamic response of a load superimposed on the steady state characteristics of that load is required for transient experimentation.

This paper analyses an approach using augmented feedback in the dead-time region to minimise current clamp with PI controllers. In spindle and other variable-speed drive applications, where the lowest speed of operation is not less than a few hundred revs/min, it may be possible to obtain the switching signals for the inverter from the motor back-emf, thus dispensing with rotor-position sensors. The proposed technique is confirmed in computer simulation. BETZ ROBERT G, ceo, inactive TOTAL PLANNING SERVICES, INC.
