Predictive Current Control with fixed switching frequency for an NPC converter

2015 IEEE 24th International Symposium on Industrial Electronics (ISIE), 2015
In this paper a Predictive Current Control strategy is proposed for constant switching frequency operation and verified with a neutral-point-clamped (NPC) converter for load current regulation and DC-link capacitor voltages balancing. The aim of this control technique is to obtain a modulated waveform at the output of the converter, whilst maintaining ...

Model Predictive Control of Master-Slave Inverters Operating with Fixed Switching Frequency

2023 IEEE 8th Southern Power Electronics Conference and 17th Brazilian Power Electronics Conference (SPEC/COBEP), 2023
This paper proposes a Fixed Switching Frequency Model Predictive Control (FSF - MPC) for Master-Slave parallel inverters in a microgrid. The Master is a grid-forming inverter with an LC output filter, and the Slave is a grid-following inverter with an output LCL filter.

Fixed switching frequency hybrid control for a permanent magnet synchronous machine

2004 IEEE International Conference on Industrial Technology, 2004. IEEE ICIT '04., 2005
In this paper, we present a novel control strategy for motor drivers, which we have called fixed switching frequency hybrid control (FSPHC). Based on models of both motor and inverter, the hybrid control uses a formal representation of the inverter-machine group behaviour.

Adaptive Power Sharing and Switching Frequency Control for Power Loss Optimization in WBG/Si Hybrid Half-Bridge Converters

IEEE transactions on power electronics, 2023
The optimization of switching frequencies and the power-sharing ratio between the silicon (Si) phase and wide-bandgap (WBG) phase are critically important for the efficiency improvement and safe operation of the WBG/Si hybrid half-bridge (HHB)-based ...

A Converter with Fixed Switching Frequency Adaptive Multi-Mode Control Scheme

2007 IEEE International Symposium on Circuits and Systems, 2007
A multi-mode adaptive control scheme to achieve high conversion efficiency over wide load range is presented in this paper. The presented controller results in improved efficiency while operating at a fixed switching frequency which guarantees maintained steady-state and dynamic performance at all load conditions. This is achieved by operating in three

Modulated Predictive Voltage Control of a Four-Leg Inverter with Fixed Switching Frequency

The Power Electronics, Drive Systems & Technologies Conference, 2020
In this paper, a novel modulated model predictive voltage control method is proposed for a two-level four-leg inverter with an output $LC$ filter. To decouple the dynamics of state variables in an output $LC$ filter and to improve the load voltage ...

Digitally-controlled PWM inverter modulatedby multi-randomtechnique with fixed switching frequency

IEE Proceedings - Electric Power Applications, 2001
A digitally controlled PWM inverter, modulated by a multi-random technique with a single fixed switching frequency, is proposed for uninterruptible power supplies. Multi-random pulsewidth modulation utilises a random phase-shift PWM scheme and a random pulse position PWM scheme, both driven at the same switching frequency.

Discrete-Time Super-Twisting Sliding Mode Current Controller With Fixed Switching Frequency for Switched Reluctance Motors

IEEE Transactions on Power Electronics, 2022
This paper proposes a discrete-time super-twisting sliding mode (DTSTSM) current controller for switched reluctance motors. A novel gain design procedure is proposed, guaranteeing a systematic and straightforward design stage. The method makes use of a cost function, enabling the gains that yield the best trade-off between reference tracking and low ...
