A Hall effect-based linear current sensor is connected between the inverter output and the grid. This current sense IC measures the inverter output current flowing into the grid.
Two external silicon carbide (SiC) diodes are therefore connected in anti-parallel for current freewheeling while avoiding problems connected to reverse recovery at MOSFET turn-on.
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
In this paper, a plug-in repetitive current controller which is composed of a proportional part and an RC part is proposed to enhance the harmonic rejection capability. The synchronized
