DESCRIPTION
Interpoint’s HUMMER™ Hold-Up Module Series provides a single
product solution to the problem of maintaining electronic system
operation during input power drop-out, typically reducing bulk
capacitance requirements by more than 80%. The HUMMER
module is compatible with the Interpoint DC/DC converters in
Section B1 that have a 28 VDC nominal input and a high input line
of 40 VDC.
The traditional procedure for providing hold-up during power loss is
to buffer the device with enough bulk capacitance to allow a
controlled shutdown to occur or an alternative power source to be
brought on line. The problem with this approach is that very large
capacitor banks are required because the capacitors are charged at
the relatively low voltage at which power fails.
The HUMMER Hold-Up Module provides an alternative with two
important advantages: 1) it effectively reduces the low line voltage
for normal DC/DC converter operation to 12 VDC thereby reducing
power drop-out events, and 2) it charges hold-up capacitors to 40
volts, reducing the capacitance needed to produce a given hold-up
time.

PERATION
The HUMMER module and two external components (a hold-up
capacitor and a diode) are connected between the line source and
the DC/DC converter as shown in Figure 3 (HUMMER Module
System Block Diagram.) If an EMI filter is employed, the HUMMER
module is connected between the filter and the converter). The
module first charges the external capacitor to 40 volts, and then
allows the converter to operate off the line voltage. When the line
voltage drops to between 12 to 18 VDC, a boost converter in the
module supplies an output at the capacitor charging voltage (40
VDC). If power fails (the input voltage drops below 12 VDC), the
converter is powered from the external hold-up capacitor.
