Description. 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.
This designer reference manual describes a DC to AC inverter for the solar panel. This design example shows how to convert the small DC voltage with highly variable power from the solar panel to the AC output voltage 230 V / 50 Hz sine shape, see Figure 1-1 . The output power is sufficient to source small AC powered appliances or lights in the

Figure 4 shows the schematic of the multilevel inverter. Figure 5 shows the efficiency of the demonstration board in relation to the output power. The maximum efficiency (approximately 99.1 percent) is achieved at around 2 kW. At full load (4 kW), the efficiency is still very high, at around 98.7. Table 1: Inverter specifications.
output are virtually always connected through a power inverter to produce the usable three-phase AC on the power grid. This particular inverter design is intended to be control-scheme agnostic; the actual operation of it will vary with different control algorithms. It is designed to be a general purpose, three phase 2.3 kW power inverter,
At full load (4 kW), the efficiency is still very high, at around 98.7 percent, which explains why this multilevel inverter can work continuously without the need for any heatsink or fan. Figure 10 Efficiency vs. power @ 40 kHz. 2.2 Eight-outputs flyback-based power supply for isolated gate-driver.
Almost any solar systems of any scale include an inverter of some type to allow the power to be used on site for AC-powered appliances or on the grid. Different types of inverters are shown in Figure 11.1 as examples. The available inverter models are now very efficient (over 95% power conversion efficiency), reliable, and economical.

2.1.1 Inverter Mode: The method, in which the low voltage DC power is inverted, is completed in two steps. The first step is the conversion of the low voltage DC power to a high voltage DC source, and the second step is the conversion of the high DC source to an AC waveform using pulse width modulation.
