Three Phase Inverter

Power loss estimation is a very crucial step in the design of power inverters and other power converters. In this paper, the estimation of power losses using MATLAB Simulink is presented. This approach allows fast estimation of losses and can lower the design time of the cooling system. With the use of a simulation approach, different parameters can be simulated to estimate losses and design the best cooling solution accurately. Characteristics of the used semiconductor in this case IGBT is used and imported to the electro-thermal simulation. This simulation consists of two main parts. The first component calculates semiconductor losses depends on the provided characteristics of the used device and his temperature. The second model calculates temperature based on the thermal model and losses produced by the first part of the simulation. Results in the form of the losses are implemented to the heat distribution simulation using Fusion 360 to simulate the temperature distribution of the used heatsink.

Three Phase Inverter

This paper takes a two-stage three-phase inverter as an example. The efficiency calculation method is analyzed in detail for the inverter, and the power losses calculation method is proposed for the second stage under SVPWM. A 10kW/380V inverter system is designed. The system efficiency and the power losses for every part are theoretically calculated. Finally, experiments on a 10 kW prototype are carried out to verify the calculation.

Three Phase Inverter

Islanding detection is an important issue for grid-connected photovoltaic (PV) generation systems. The paper puts forward a new composite islanding detection method combining active current disturbance and reactive current disturbance. This islanding detection method for three-phase inverter is simulated in the Matlab/Simulink environment. Simulation results show that, when the inverter output and the load power are balanced, the new islanding detection method can detect islanding quickly with little influence on the power quality.

This paper presents a framework to carry out the BLDC motor characteristics using code composer studio software interfaced with a GUI named InstaSpinBLDC. The three phase BLDC motor is driven with DRV8312 and a control card TMS320F28069 is used to run the sensor InstaSpin BLDC. This proposed work is intended to track the dynamic performance and lower the minimum operating speed with respect to control modes. Four control modes have been modelled in conjunction of three phase inverter for BLDC motor. The simulation includes all realistic values and components of the motor. Three-phase inverter and its control algorithm are modeled and simulated using MATLAB Simulink. Hardware results have been presented along with the simulation results.

Three Phase Inverter

BLDC motors are characterized by electronic commutation, which is performed by using an electric three-phase inverter. The direct control system of the BLDC motor consists of double loops; including the inner-loop for current regulating and outer-loop for speed control. The operation of the current controller requires feedback of motor currents; the conventional current controller uses two current sensors on the ac side of the inverter to measure the currents of two phases, while the third current would be accordingly calculated. These two sensors should have the same characteristics, to achieve balanced current measurements. It should be noted that the sensitivity of these sensors changes with time. In the case of one sensor fails, both of them must be replaced. To overcome this problem, it is preferable to use one sensor instead of two. The proposed control system is based on a deadbeat predictive controller, which is used to regulate the DC current of the BLDC motor. Such a controller can be considered as digital controller mode, which has fast response, high precision and can be easily implemented with microprocessor. The proposed control system has been simulated using Matlab software, and the system is tested at a different operating condition such as low speed and high speed.
