Product Description
The VI BRICK BCM Array is a high efficiency (>95%) Sine Amplitude Converter (SAC) operating from a 360 to 400 Vdc primary bus to deliver an isolated 45-50 V nominal, unregulated secondary. The SAC offers a low AC impedance beyond the bandwidth of most downstream regulators, meaning that input capacitance normally located at the input of a regulator can be located at the input to the SAC. Since the K factor of the BC384R480T065VM-00 is 1/8, that capacitance value can be reduced by a factor of 64x, resulting in savings of board area, materials and total system cost.

CNTRL - Enable / Disable
The Enable / Disable signal is a multifunction node that provides the following functions: Enable / Disable - If CNTRL is left floating, the module output is enabled. Once this port is pulled lower than 1.95 Vdc with respect to -In, the output is disabled. This action can be realized by employing a relay, opto-coupler, or open collector transistor. This signal should not be toggled at a rate higher than 1 Hz. CNTRL should also not be driven by or pulled up to an external voltage source. Primary Auxiliary Supply - CNTRL can source up to 10 mA at 5.0 Vdc. CNTRL should never be used to sink current. Alarm - The module contains circuitry that monitors output overload, input over voltage or under voltage, and internal junction temperatures. In response to an abnormal condition in any of the monitored parameters, CNTRL will toggle.
Figure 15 -- Temp measurement location
+In / -In - DC Voltage Input Ports
The BCM Array input voltage range should not be exceeded. An internal under / over voltage lockout-function prevents operation outside of the normal operating input range. The module turns on within an input voltage window bounded by the "Input undervoltage turn-on" and "Input over-voltage turn-off" levels, as specified. The module may be protected against accidental application of a reverse input voltage by the addition of a rectifier in series with the positive input, or a reverse rectifier in shunt with the positive input located on the load side of the input fuse.
+Out / -Out - DC Voltage Output Ports
Multiple pins are provided for the +Out and -Out connections. They must be connected in parallel with low interconnect resistance. The low output impedance of the module reduces or eliminates the need for limited life aluminum electrolytic or tantalum capacitors at the input of POL converters. Total load capacitance at the output of the device should not exceed the specified maximum. Owing to the wide bandwidth and low output impedance of the BCM Array, low frequency bypass capacitance and significant energy storage may be more densely and efficiently provided by adding capacitance at the input.

SPECIFICATIONS
CURRENT SHARING The SAC topology bases its performance on efficient transfer of energy through a transformer, without the need of closed loop control. For this reason, the transfer characteristic can be approximated by an ideal transformer with some resistive drop and positive temperature coefficient. This type of characteristic is close to the impedance characteristic of a DC power distribution system, both in behavior (AC dynamic) and absolute value (DC dynamic). When connected in an array (with same K factor), the BCM module will inherently share the load current with parallel units, according to the equivalent impedance divider that the system implements from the power source to the point of load. It is important to notice that, when successfully started, BCMs are capable of bidirectional operations (reverse power transfer is enabled if the BCM input falls within its operating range and the BCM is otherwise enabled). In parallel arrays, because of the resistive behavior, circulating currents are never experienced, because of energy conservation law. General recommendations to achieve matched array impedances are (see also AN016 for further details): * to dedicate common copper planes within the PCB to deliver and return the current to the modules * to make the PCB layout as symmetric as possible * to apply same input/output filters (if present) to each unit
