Grid Connected Inverter Reference Design (Rev. D)
Description This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). The design supports two modes of operation
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
In this mode, the inverter is connected to the grid at PCC and it transfers the generated power from the DC side to the AC side, i.e., grid and AC loads (Ahmed et al. 2011). The voltage reference is taken as per the grid side requirements for inverter controller.
On-grid PV systems only generate energy when the utility power grid is available . This converters are traditionally voltage source . The ideal grid-connected PV inverter can not only provide high-quality power to the power grid but also can support the frequency and voltage amplitude of the power grid .
Along with that, it keeps a track on harmonics and reduces the harmonics as per grid standards (Zmood and Holmes 2003). Inverter switches play a significant part in implementing the control technique. When grid-connected inverters intentionally separate themselves from the PCC, through opening the controlled switch, they operate autonomously.
Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.
The user must not touch the board at any point during operation or immediately after operating, as high temperatures may be present. Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid.
