چکیده
Power battery test equipment is widely used to produce and new energy vehicles storage containers. To address the problem of DC bus voltage fluctuations that affect accuracy output current, a high-accuracy control strategy based on nonlinear extended state observation (NLESO) terminal silding mode controller (TSMC) load current estimation. Simulation experimental results show has good suppression effect fluctuation can effectively improve side current. Grid differential feedforward adopted, which achieve fast in power meet high precision requirements system bus.

Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملVoltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer
Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...

متن کاملA Modified Series Z-Source Inverter Based on Switched Inductors with High Voltage Gain and Reduced Voltage Stress on Capacitors
In this paper, a series Z-source inverter based on switched inductors cell is proposed for the first time. This inverter is able to increase the voltage gain in comparison to the conventional Z–source inverters in additon to solve the ST (shoot-through) state’s problems. In this inverter, the value of voltage gain is increased by increasing the number of used diodes and inductors in the switche...
