This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). The design supports two modes of operation for the inverter: a voltage source mode using an output LC filter, and a grid connected mode with an output LCL filter. [pdf]
The communication base station installs solar panels outdoors, and adds MPPT solar controllers and other equipment in the computer room. The power generated by solar energy is used by the DC load of the base station computer room, and the insufficient power is supplemented by energy storage devices. [pdf]
Diversity techniques To improve the quality of the received signal, often two receiving antennas are used, placed at a distance equal to an odd multiple of a quarter of the corresponding wavelength. For 900 MHz, this wavelength is 33 cm. This technique, known as antenna diversity or space diversity, avoids interruption caused by path fading. The antennas can be spaced horizontally or vertically. Horizontal spacing requires more complex installation, but brings bette. [pdf]
As it is established, the high efficiency, high energy density, and increased charge acceptance account for lower generator runtime and lesser fuel cost. Additionally, the reduced site visits for performan. [pdf]
