“…In paper [13] [14], SVPWM is proposed for three-phase three-level inverter by simplifying the three-level SVPWM into a two-level SVPWM diagram. In this, three-level SVPWM diagram is modified into two-level SVPWM diagram by constructing many small hexagon from three-level SVPWM diagram and dwelling times of three-level voltage vectors are calculated in same manner as two-level.…”

A simplified Space Vector Pulse Width Modulation (SVPWM) is proposed for three-level five-phase inverter. The proposed method generates the duty cycle of three-level inverter switches based on dwell times of two-level inverter and carrier index. The proposed method automatically determines the eligible vectors, region and switching sequence of optimized five vectors based on modulation index. Out of the 243 available vectors, 113 most eligible vectors are used for generation of desired voltage reference in main subspace while zeroing the average voltage in the auxiliary subspace by using proper switching sequence. This method also uses the redundant vectors in each sub-cycle thus balances the DC-link capacitor voltages and no additional algorithm or techniques are needed to balance DC-link capacitor voltage. The identification of reference location with carrier index using signum function simplifies the algorithm implementation. Thus the proposed method eases the implementation of optimum five vectors to a greater extent. Based on only changing the carrier index the proposed method can be easily extended for any multi-phase multi-level (5, 7 ...n) inverter. The simulation and hardware results of three-level fivephase inverter validate the proposed simplified method.

“…The suggested hybrid switches are not practically recommended as the inverter phase module switches will not have the same characteristics which will complicate the overall inverter design and limits it power rating as declared by the authors. A recent driver circuit is presented in Ramirez et al (2012) which require two IR2110 to drive each inverter leg as shown in Figure 5. The driver circuit requires four separate power supplies each for one IGBT.…”

This paper presents a low-cost IGBT driver circuit for a three-level neutral point clamped (3L-NPC) converters. The driver circuit is built with IR2110 with an external dead-time circuit based on Schmitt trigger. Originally, the IR2110 is designed to drive two switches of a half-bridge inverter in a complementary manner. Two IR2110 are used to drive one phase of the 3L-NPC converter. Each pulse leading edge is delayed for around ten microseconds to prevent the shoot-through phenomenon. The circuit manipulates the pulses generated from the digital controller is introduced in details. The low and high voltage side of the driver circuit are optically isolated. The proposed circuit design is experimentally tested its applicability for driving 3L-NPC converters is verified.

Abstract:The main objective of the present work is to apply a sliding mode controller (SMC) to medium voltage and high power output energy recovery Li-ion power accumulator battery pack testing systems (ERLPABTSs), which are composed of a three-level neutral-point-clamped (NPC) three-phase voltage source inverter (VSI) and a two-level buck-boost converter without an isolating transformer. An inner current decoupled control scheme for the aforementioned system is proposed and two sliding mode planes for active and reactive current control are designed based on the control scheme. An optimized switching table for current convergence is used according to the error sign of the equivalent input voltage and feedback voltage. The proposed ERLPABTS could be used to integrate discharging energy into the power grid when performing high accuracy current testing. The active and reactive power references for the grid-connected inverter are determined based on the discharging energy from the DC-DC converter. Simulations and experiments on a laboratory hardware platform using a 175 kW insulated gate bipolar transistor (IGBT)-based ERLPABTS have been implemented and verified, and the performance is found satisfactory and superior to conventional ERLPABPTS.
