Use voltage-adjusting power supply to charge the inverter:
The right selection of the voltage-adjusting power supply depends on the supply power of
the inverter. Single phase 220V AC/2A power surge is applied to the inverter of
single/three-phase 220VAC. The inverter of single/three-phase 220V AC can apply single
phase 220V AC/2A power surge(L+ to R, N to S or T). All DC bus capacitors can charge at
the same time because there is one rectifier.
High-voltage inverter needs enough voltage (for example, 380V) during charging. The small
capacitor power (2A is enough) can be used because the capacitor nearly does not need
current when charging.
The operation method of inverter charging through resistors (LEDs):
The charging time is at least 60 minutes if charge the DC bus capacitor directly through
supply power. This operation is available on normal temperature and no-load condition and
the resistor should be serially connected in the 3-phase circuits of the power supply:
a)380V driven device: 1k/100W resistor. LED of 100W can be used when the power
voltage is no more than 380V. But if used, the light may be off or weak during charging.
b) 660V driven device: 1k/160W resistor.
