Abstract: A motor simulator without requiring a motor is a testing motor controller used for inputting a driving signal according to a power supply driving signal, feeding back a status response of a dynamic calculator of the motor simulator, outputting a voltage and current reference command value required by the motor simulator to the motor simulator, so that the dynamic calculator and the electric power converter installed in the motor simulator generate a voltage and a current of an actual motor in an operating status. Therefore, the testing motor controller keeps converting and adjusting the electric energy for driving an operation of the motor simulator according to a status response fed back by the dynamic calculator of the motor simulator, so as to achieve a control function of the testing motor controller for testing the rotation speed and positioning of the motor.

Abstract: The present invention relates to an inverter system for energy-storing microgrid and a controlling method thereof, wherein the inverter system for energy-storing microgrid is integrated with a detecting module, a controlling and processing module, a visual resistor algorithmic processor, and a PWM signal generator. Moreover, the controlling and processing module is installed with a power-voltage reducing function and a reactive power-frequency reducing function for making the controlling and processing module be able to properly distribute the intensity and output ratio of all the output currents of the inverters according to the charge states of battery modules and load currents. Therefore, the current supply of each of the parallel connected inverters in the inverter system can be automatically distributed and modulated for effectively providing necessary electric power to each of connected loads, respectively.
