5.Operation
BIC-2200 possesses AC to DC and DC to AC two way conversion functions. The conversion direction can be automatically detected and controlled by BIC-2200's internal firmware or manually switched by users according to different application requirements. Before entering detailed function explanation. Please refer to following definitions. AC to DC (Energy absorbing and charging/ power supplying): The BIC-2200 converts AC energy from the grid into DC energy for the battery or the loads. The operation principle is the same as an ordinary power supply or a charger.
Energy absorbing
charging/power supplying

AC
DC
DC to AC (Energy recycling and discharging): Opposite to the AC to DC conversion, the BIC-2200 converts DC energy from the battery or loads into AC energy, then feeding back to the grid. AC output synchronization range is 180Vac~264Vac/47Hz~63Hz, the bidirectional power supply can work normally as long as the AC gird is within the range.

l "Target voltage" is the DC voltage setting of the bidirectional supply, when the DC end voltage is different from the "target voltage", the internal firmware will switch between two conversion functions of AC to DC or DC to AC. "Target voltage" is adjustable by the SVR.
l When the "target voltage" is higher than the battery voltage or application equipment voltage, the BIC-2200 operates in AC to DC conversion.
l When the "target voltage" is lower than the battery voltage or application equipment voltage, the BIC-2200 operates in DC to AC conversion.
NOTE: During this mode, AC to DC or DC to AC conversion is judged by the internal firmware. Active control signal (e.g. C/D control) will not take effect in this mode.

NOTE: Analogy signals cannot be used to adjust parameters of charging voltage (VOUT_SET)/discharging voltage (REVERSE_VOUT_SET) and charging current (IOUT_SET)/discharge current (REVERSE_IOUT_SET), but only control AC to DC or DC to AC conversion.

5.1.3.3 Notes on battery mode In bi-direction battery mode, although users can determine direction of the conversions on their demand, however if the setting voltage does not match the actual DC end voltage, AC to DC (charging) or DC to AC (discharging) conversion may not work as expected. Here are examples that will cause conversion errors.
1. During AC to DC conversion (C/D control = High or
DIRECTION_CTRL = 00h), if battery voltage is higher than
the value of command VOUT_SET (charge voltage), the
BIC-2200 will perform DC to AC conversion instead, but
limiting discharge current at 5% of rated current. If you
want to ensure AC to DC conversion working properly,
please make sure value of command VOUT_ SET is higher
5
than the battery voltage.
2. During DC to AC conversion (C/D control =Low or DIRECTION_CTRL = 01h), if battery voltage is lower than the value of command VOUT_SET_REV, the BIC-2200 will perform AC to DC conversion instead, but then limiting charge current at 5% of rated current. To ensure DC to AC conversion working properly, please make sure value of command VOUT_ SET_REV is lower than the battery voltage.

5.2 Inrush Current Limiting
l Built-in AC inrush current limiting circuit
l Since the inrush current limiting circuit mainly consists of a NTC
5
thermistor and a relay, inrush current will be much higher than the
specified value if the thermistor in AC side is not allowed sufficient
time to cool down. After turning off the supply, a 10 second cool down
period is recommended before turning on again.
5.3 Power Factor Correction (PFC)
l Built-in active power factor correction (PFC) function, power factor (PF) will be 0.95 or better at full load condition in AC to DC or DC to AC conversion. PF will be less than 0.95 if it is not at full load condition during AC to DC or DC to AC conversion.
5.4 Fan Speed control
l Built-in fan speed control circuit, fan speed changes automatically depending on internal temperature.

5.5 Fault Signal
l Fault signal is used to inform application equipment that whether it is energy recyclable. When it is OLP, SCP or OTP, BIC-2200 will send a high level of fault signal 100ms in advance to notify the application before shutting down the supply. A fault signal will send out at the same time of shutting down operation in the reset of protection (e.g. AC_fail).
l Maximum output current 4mA.

5.9 Parallel Operation
BIC-2200 has the built-in active current sharing function and can be connected in parallel, up to 5 units, to provide higher output power as exhibited below:
l The power supplies should be paralleled using short and large diameter
wiring and then connected to the load.
5
l In parallel connection, power supply with the highest output voltage will
be the master unit and its Vout will be the DC bus voltage.
l The total output current must not exceed the value determined by the
following equation:
Maximum output current at parallel operation=(Rated current per unit)
x (Number of unit) x 0.95
l When the total output current is less than 5% of the total rated current,
or say (5% of Rated current per unit) x (Number of unit) the current
shared among units may not be balanced.
l Under parallel operation ripple of the output voltage may be higher than
the SPEC at light load condition, It will go back to normal ripple level
once the output load is more than 5%.

Note : The conversion of setting and reading values is defined as following: Actual value = Communication reading value × Factor (F value). Among them, Factor needs to refer to the definition of SCALING_FACTOR in each model list. EX: VDC_real (actual DC voltage) = READ_VOUT x Factor. If the Factor of READ_VOUT of a certain model is 0.01, the communication reading value is 0x0960 (hexadecimal) 2400 (decimal), then VDC_real = 2400 × 0.01 = 24.00V.

6.Protections and Trouble Shooting
6. 1 Protections
6.1.1 Anti-islanding Protections BIC-2200 is designed to refer to IEC 62116(2008), the supply shuts off within 2 seconds when AC is cut or abnormal. Please be aware that it is necessary to install an AC circuit breaker that complies with grid-tie standard in your country before the supply.
6.1.2 Over Temperature Protection (OTP) and Alarm
Built-in thermal detection circuit, once the internal temperature
exceeds a threshold value, the supply will shut down automatically (the
fans will still be running to cool down the supply). Please switch off the
supply, remove all possible causes and then leave the supply cooling
down to a normal working temperature (approximate 10 minutes - 1
hour) before repower on again.
Maximum output current 4mA.

6.1.3 AC Fail Protection When AC voltage/frequency is abnormal, BIC-2200 will enter protection mode to prevent damaging itself or affect quality of the grid no matter which conversion it is, D/A or A/D. The supply will restore automatically when AC voltage/frequency back to normal.
6.1.4 Short Circuit Protection When there is short circuit at AC/DC end of BIC-2200, the supply will enter protection mode and shut down. Repower on to restore after short-circuit condition is resolved.

6.1.5 Over Current Protection
In AC to DC conversion, when the load current exceeds 110%±5%
of the rated current, protection mode will be triggered. Repower
on to restore after over-current condition is resolved.
6.1.6 DC Over Voltage Protection When the DC end voltage is too high, the DC over-voltage protection circuit will be triggered. Repower on to restore after over-voltage condition is resolved.
