ECI TECHNOLOGY
10 - Bravo 10 - 48/230 - User manual - v1.2
4. ECI TECHNOLOGY 1
Inverter modules carrying the ECI logo and the EPC mark are triple port converters (AC in, DC in, AC out). Sinusoidal
output is converted from Mains or/and DC.
The block diagram below gives an explicit description of the topology and operation.
The module is built around the following sub-converters
•AC to DC at input
•DC to DC at input
•DC to AC at output
The energy can flow either from the AC source or the DC source under the control of the local DSP controller. Thanks to
internal energy buffering, the output sine wave is constant and disturbance free regardless of the active source.
The BOOST functionality multiples the nominal current for a period of 20 ms (max) in the event of down stream failures.
The upstream breakers do not have to be oversized to prevent tripping. The overload capacity is 150% for 15 seconds.
The ECI works according to True Redundant Structure (TRS) that features decentralized and independent logic, redundant
communication bus and three internal levels of disconnection to isolate a module after internal failure.
This functionality is included in every inverter module. Running them in parallel provides a modular system with, no
single point of failure, always-conditioned output, high system efficiency and 0 ms source transfer time.
1 Information and data given in this chapter is intended to serve as an overview of the ECI Technology. Detailed features and parameters for each individual
module type in the range may differ and should be referred to in the dedicated data sheet.

ECI TECHNOLOGY
11 - Bravo 10 - 48/230 - User manual - v1.2
4.1 On-line Mode
DC is the primary source of supply whilst Mains (AC) works as the secondary source. Switching time between DC input
and AC input is 0 ms (source transfer). The power delivered by the DC source (usually a battery, but possibly any other
type of DC generator) is converted to provide regulated and transient-free power to the load. In the event of a short
circuit on the load side, the boost is automatic, timely and energized for a specific duration to trip downstream protective
devices.
4.2 Safe mode
Safe mode uses DC as the primary source of supply while Mains (AC) is on standby.
Mains (AC) is normally disconnected through an internal inlet relay and is only connected when down stream clearance
is required (boost) or if DC is unavailable.
The transfer between DC and AC results in a typical transfer time of 10 ms.
Typically the safe mode is used in extremely harsh environments such as railways. Under such conditions, it provides
extra isolation against mains-borne disturbances.
4.3 EPC-mode
Mains input (AC) is the primary source whilst DC works as backup.
The ECI is designed to operate on Mains on a permanent basis and to deliver output voltage conditioned with low THD.
The output sine wave is physically independent of whether the source is AC (or) DC. If the Mains is out of tolerance
or goes down, the converter seamlessly switches to DC and the converter operates in “Back-up mode” (Changeover
switching time is 0 ms).
As soon as the Mains returns to its valid range, the EPC mode is automatically resumed.
The EPC mode offers higher efficiency (up to 96% depending on the model) without compromising the purity of the
output sine wave.
Remarks: REG modules:
Inverter modules carrying the ECI logo together with the REG mark work only with DC input. Sinusoidal output is converted
from DC with the module operating as a traditional inverter. EPC mode and the boost are not available with REG modules.
4.4 Mix mode & Walk-in mode
Under some circumstances the DC and AC sources can be combined. The sequence is defined by a user selectable set
of parameters. Start, control and exit are fully automatic.
A specific example of Mix-mode is the Walk-in mode where the transfer from DC source to AC source is ramped up
within a fixed and adjustable period of time.

5.3 Manual By-Pass
The manual by pass operates via manually operated switches to create a short circuit from the
AC main input directly to the output AC distribution. Standard manual by-pass is “Make before
Break”. When engaged or disengaged, no disturbance is transmitted to the load.
When MBP is engaged, inverter modules are switched off and can be removed without impacting
the load. The battery supply is not physically disconnected. After disconnecting the battery
supply (by opening the battery breakers), the shelf section is safe for maintenance.
Warning: When the system is in by-pass, the load is subjected to AC main disturbances. Before engaging manual
bypass, make sure the voltage difference between AC IN and AC OUT should be less than 5 Vac to limit the inrush
current.
