Description This reference design implements single-phase inverter (DC/AC)
control using a C2000™ 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.
High-efficiency, low THD, and intuitive software make this design
attractive for engineers working on an inverter design for UPS and
alternative energy applications such as PV inverters, grid storage, and
micro grids. The hardware and software available with this reference design
accelerate time to market
Claim 97-98% efficient.
Three phase version
10kW 3-Phase 3-Level Grid Tie Inverter Reference Design for Solar String
This verified reference design provides an overview on how to implement a
three-level three-phase SiC based DC:AC grid-tie inverter stage.Higher
switching frequency of 50KHz reduces the size of magnetics for the filter
design and enables higher power density. The use of SiC MOSFETs with
switching loss ensures higher DC bus voltages of up to 1000V and lower
switching losses with a peak efficiency of 99 percent. This design is
configurable to work as a two-level or three-level inverter.The system is
controlled by a single C2000 microcontroller (MCU), TMS320F28379D, which
generates PWM waveforms for all power electronic switching devices under
all operating modes.
- Rated nominal/max input voltage at 800V/1000VDC
- Max 10kW/10KVA output power at 400VAC 50/60Hz grid-tie connection
- Operating power factor range from 0.7lag to 0.7lead
- High voltage (1200V) SiCMosFET based full bridge inverter for peak
efficiency of 99%
- <2% output current THD at full load
- Isolated current sensing using AMC1301 for load current monitoring
- Isolated driver ISO5852S with reinforced isolation for driving High
voltage SiC MOSFET and UCC5320S for driving middle Si IGBT
