This paper analyzes the two commonly used current control methods for high power, low switching frequency applications involving half bridge inverter. First, the problem of voltage balancing of two DC link capacitors in the half bridge inverter has been discussed. The two current control methods used for the comparison are hysteresis current control and ramp comparison current control methods. It...
In this paper, an isolated wind energy conversion system (WECS) based on the cascaded H-bridge multilevel inverter (CHBMLI) topology employing a permanent magnet synchronous generator (PMSG) driven by a variable speed wind turbine and feeding high power single-phase local loads has been proposed. A seven-level cascaded H-bridge inverter employing phase-shifted multi-carrier pulse width modulation...
This paper proposes a generalized hysteresis current controlled three level voltage source inverter (VSI) based single phase shunt active power filter (SAPF). The three level inverter topologies considered in this paper are H-bridge and diode clamped inverters. A generalized hysteresis current control with multiband hysteresis modulation has been used to control the voltage source inverters in the...
In this paper a cascaded H-bridge inverter topology is used in a distribution static compensator (DSTATCOM). A new multiband hysteresis algorithm is used to control the switches of the cascaded H-bridges leading to multilevel output of the inverter. The algorithm requires hierarchal switching of each H-bridge. Sequential change in the hierarchy facilitates equal charging and discharging of each capacitor...
