1 System description
A general description of the system is shown in Figure 2 with a block scheme representing
hardware implementation.
Figure 2. Block scheme of hardware implementation
It consists of 5 boards as listed below:
● Main power board
● Multi-output power supply board
● Control and signal conditioning board
● Output sensing and relay board
● Input current sensing board.
The system may be completed by adding two additional boards with input and output EMI
filters which, at the moment, are not included in the final prototype.
The main power board is a dual-stage converter using DC-DC to adapt voltage levels and
impedance from the PV array and a sinusoidal PWM DC-AC to perform grid connection at
230 Vrms and 50 Hz, [see References 3]. Gate driving circuitry, input and output voltage
sensors of the DC-DC converter, as well as high frequency (HF) transformers, are also
placed on the power board. The principle reason for using a HF transformer is the galvanic
isolation provided between the PV module and the grid, to minimize the risk of hazardous
operations on the PV side caused by a fault on the grid side; voltage step-up and also
interruption of the resonance path formed by the parasitic capacitances to ground of the PV
array and the inductance of the LCL filter. Another advantage is the elimination of high
common mode currents allowing the use of unipolar pulse-width modulation for the inverter
with a consequent reduction in current harmonic content compared to bipolar pulse-width
modulation, [see References 4, 5].
Both the multi-output power supply board and control board are connected to the main
power board by means of a 34-pin connector. In this way, the connection/disconnection of
the ancillary boards is very easy and allows the separation of debug and characterization.
