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.

Abstract: An apparatus for current estimation of a DC/DC converter includes a current sensing unit, a signal sampling unit, and a current estimator. The current sensing unit is for sensing a current passing through a switch of the DC/DC converter and converting the current into a voltage signal. The signal sampling unit, coupled to the current sensing unit, is for sampling the voltage signal so as to output a sampled signal. The current estimator, coupled to the signal sampling unit, is for determining a signal indicating estimated magnitude of an inductor current of the DC/DC converter, based on the sampled signal, a scale factor of the current sensing unit, a duty ratio of a driving signal for controlling the switch, an input voltage and an output voltage of the DC/DC converter. An apparatus for current estimation that can further control an averaged current of a DC/DC converter.

Abstract: A phase-locked loop method for use in utility electricity parallel-connection system is introduced. The phase-locked loop method comprises a conversion signal generating step, an error calculating step, a frequency correction signal obtaining step, an angle signal obtaining step, and a synchronous signal generating step to not only calculate an error value by detecting a utility electricity voltage, but also reduce or return-to-zero the error value by proportional integral adjustment. With the steps, the phase-locked loop method achieves synchrony precisely by eliminating input utility electricity voltage distortion and frequency variation. Furthermore, the phase-locked loop method advantageously features quick response and a wide frequency range and therefore is effective in tracking power generation facilities, such as a diesel generator, and expanding inverters.
