The demand for high-efficiency DC-DC converters is growing rapidly, especially for use in batteryoperated. To increase the supply DC input from power sources such as batteries, solar panels, and output from rectifiers, DC supplies, or DC generators, boost converters are used. This research designed a 24 VDC to 400 VDC voltage booster, tested using a 220 Vac amplification inverter system with an output of 220 Vac. The EGS-002 inverter used in this research was equipped with a Sinusoidal Pulse Width Modulation (SPWM) driver, a method that produces an output signal in the form of a pure sinusoidal wave. The test was carried out by connecting the inverter circuit directly with a voltage booster circuit in the form of a 400VAC step-up transformer to produce 24 VDC input and 50-400VDC output voltages. The length, width and height of the voltage booster are 55 cm x 35 cm x 15 cm, equipped with a cooling fan consisting of a 24V battery charger, and 4 VDC output terminals.

“…The vigorous development of wind power, PV, and other new energy sources is an important way to establish a new power system and promote the realization of the "carbon peak and carbon neutralization" development goal [1], However, the large-scale access of wind power and PV to the inverter interface emphasizes the power electronic characteristics of the power system, lowers the equivalent inertia of the system, and deteriorates the dynamic response to frequency [2][3][4], Therefore, the successful realization of low voltage ride-through in a short period of time has become an essential criterion to measure grid connection [5], In recent years, grid-connected inverters represented by virtual synchronous generators (VSG) have garnered more attention [6][7][8], Grid-connected inverters can offer the necessary inertia and damping bracing for the system to alleviate the stability concerns caused by traditional grid-connected inverters by configuring energy storage or power standby.…”

There are many problems in optical storage systems, including fault ride-through and disturbance, inadequate DC bus voltage support, and high state variable overshoot. The main problem is caused by the slow dynamic reaction speed of the energy storage system based on traditional PI control to the DC voltage of the optical storage system. A hybrid optical storage system control optimization strategy based on a DC virtual synchronous machines and improved model predictive control (MPC) was proposed in the paper as a solution to the aforementioned issues. A strategy based on DC virtual synchronous generator can improve the damping braces and overshoot suppression of DC voltage fluctuation during the disruption process of the energy storage system in the optical storage system. The dynamic response speed of energy storage in optical storage systems may be further increased based on the improved MPC. The effectiveness and validity of the control strategy proposed in the paper were verified by the simulation examples.

This paper proposes a doubly-fed induction generator (DFIG) model built on three simulation platforms: Maxwell, Simplorer and Simulink. It can solve the overall modeling problem of the DFIG system effectively. In this paper, the generator physical simulation model (rotating shaft, rotor, stator and winding) are first established in Maxwell. Then, the internal (stator/rotor winding) and external circuit of DFIG are connected in Simplorer. The external circuit includes converter (generator side and grid side), filter, transformer and grid. Moreover, both the generator-side converter and the grid-side converter are controlled by Simulink. Finally, the simulation calculation study on the 5.5kW DFIG are carried out to validate the theoretical analysis. It is shown that SAGE causes distortion of the air gap magnetic field, the magnetic flux density (MFD) is inversely related to air gap changes. In addition, with the increase of SAGE, the curve of electromagnetic torque (EMT) moves down and rotor unbalanced magnetic pull (UMP) fluctuations become more obvious. The model can simulate the DFIG system accurately and effectively. And the simulation results are consistent with the theoretical derivation, which proves the validity of the model. This provides an effective method for the whole simulation and fault analysis of DFIG system.
