   NOVEL GATE POWER SUPPLY CIRCUIT USING SNUBBER CAPACITOR ENERGY FOR SERIES-CONNECTED GTO VALVES
By H.Okayama; T.Tsuchiya; M.Kimata. [View]
[Download]

Abstract: In this paper, we propose a novel gate power supply circuit for series-connected GTO valves. The main feature of our circuit is the configuration itself that a power supply circuit is integrated into a snubber circuit of each GTO. A part of energy stored in a snubber capacitor is transferred to a power supply capacitor and the transferred energy is provided for a gate drive circuit. An optimal design of our circuit is represented according to a gate drive power which is necessary for each of series-connected GTOs. We verify the availability of our circuit using several successful simulation and experimental results.

   STATE-SPACE ANALYSIS OF DIODE-CLAMPED MULTILEVEL VOLTAGE SOURCE INVERTERS FOR STATIC VAR COMPENSATION
By O. Pollakowski; H. Pouliquen; W. Schumacher [View]
[Download]

Abstract: Multi-level voltage-source-inverters are particularly well suited for high voltage high power applications, because there is no need for direct series connection of switching devices and for complicated magnetic circuits. This paper presents a complete state-space description of a diode-clamped multi-level voltage-source inverter. Based on this analysis a PI-state-space controller is designed in order to clamp the highly oscillatory modes inherent in high power converters. Also, the problem of de-voltage balance is discussed for a three-level inverter.

   CONTROL OF SERIES MULTIPLE CONVERTERS BY LINEAR STATE FEEDBACK DECOUPLING
By O. Tachon; M. Fade; T. Meynard [View]
[Download]

Abstract: The paper presents the study of control laws applied to series multicell converters. This multi-variable system requires control laws based on linear state feedback decoupling to ensure a selective interaction between inputs and outputs and assign the dynamics of state-variables.
