Operating principles
Figure 2: Single-wire diagram of a standard SUNWAY TG TE inverter
The SUNWAY TG TE inverters include the following functional blocks:
DC Input Unit
The DC Input Unit allows connecting the inverter to the photovoltaic generator. It is provided with 8 fuse-
protected inputs, on-load switch, input EMI filters and SPDs. It checks the ground isolation of the PV
generator.
Static Converter
The Static Converter comprises the forced switching IGBT stack and the control board. The Static Converter
implements the most advanced features of the inverter, such as the control logics, the current and voltage
measures, the interface protections integrated into the control software, the autodiagnostics functions and
the serial communications.
Output Filter
The Output Filter transforms the PWM output of the converter into sinusoidal voltage.
AC Output Unit
