1.
Inverter Output Voltage Adjustment
- When the inverter is running, connect an AC voltmeter to the inverter outputs (TP3, TP4 and TP5 on
ADVS01-R1 board).
- Keeping VR2, VR4, and V6 at approximately their mid-position, adjust the output voltages (roughly) to
their nominal value using VR7.
- Then re-adjust each phase voltage separately, again using VR2, VR4 and VR6 to their exact values
this time.
2.
DC Balance Adjustment
- When the inverter is running, connect a DC voltmeter to the inverter outputs (TP3, TP4 and TP5 on
ADVS01-R1 board)
- Adjust the DC voltage component of each phase of the inverter output to be ZERO, using VR1, VR3
and VR5.
3.
Inverter Output PLL Frequency Adjustment (for 50Hz nominal value)
- When the inverter is running, connect a frequencymeter to one of the inverter output phases (either
one of TP3, TP4 or TP5 on ADVS01-R1 board)
- Connect TP18 to TP12 (+12V) using a jumper wire and adjust the frequency to 51.4+/-0.1Hz using
VR8.
- Disconnect TP18 from TP12 and connect it to TP9(0V) this time (TP18-TP9) and check if the output
frequency is 48.6+/-0.1Hz.
- Repeat the adjustment procedure until you have equal frequency deviation around the center
frequency (50Hz)
- Let TP18 be NOT CONNECTED to anywhere and see that the inverter output frequency is equal to
the bypass supply (line voltage) frequency.
4.
Inverter Output Synchronization Adjustment
- Connect an AC voltmeter across the L3 phase of the inverter output (TP3 on the ADVS01-01 board)
and the L3 phase of the bypass input (TP6 on the ADVS01-01 board).
- Adjust VR9 to minimize the measured AC voltage across these points.
