120 - 192 Watt 10:1 DC-DC Converters

HP Series

These extremely compact DC-DC converters incorporate all

necessary input and output filters, signaling and protection

features, which are required in the majority of applications.

The converters provide important advantages, such as flexible

output power through total current limitation, extremely high

efficiency, excellent reliability, very low ripple and RFI noise

levels, full input-to-output isolation, negligible inrush current,

soft start, over temperature protection, interruption time, and

input over- and undervoltage lockout.

HP Series

120 - 192 W 10:1 DC-DC Converters

Functional Description

The converters are designed using transformers with planar technology. The input voltage is fed to a booster, which generates

a voltage of approx. 70 V. If

is higher, the booster becomes simply a diode. The storage capacitor

is charged by a current

source to max. 70 V and enables the powertrains to operate during the specified interruption time. The resulting intermediate

voltage, between 45 V (during interruption time) and 154 V, supplies the powertrains.

There are two powertrains fitted to a converter, each consisting either of a regulated single output with synchronous rectifier or of

a regulated main output with a tracking 2

output.

As part of a distributed power supply system, the low-profile design significantly reduces the required volume without sacrificing

high reliability. The converters are particularly suitable for 19” rack systems occupying 3 U / 4 TE only, but they can also be chassis-

mounted by screws or fitted with a heat sink. Connector type is H15. The fully enclosed Aluminum case acts as heat sink and RFI

shield, such protecting the converter together with the coating of all components against environmental impacts. The converters

are equipped with two independent forward converters, switching 180° phase-shifted to minimize the input ripple current. These

two forward converters are called “powertrains” (PT), exhibiting either a single output with synchronous rectifier or two isolated

outputs, one fully regulated and the other one tracking (semi-regulated), thus providing up to four output voltages. The output

power may be flexibly distributed among the main and the tracking output of a double-output powertrain. Close magnetic coupling

in the transformers and output inductors together with circuit symmetry ensure small deviation between main and tracking output.

The low input capacitance results in low and short inrush current. After the isolating transformer and rectification, the output filter

reduces ripple and noise to a minimum without affecting the dynamic response. Outputs 3 and 4, if available, are tracking (semi-

regulated). An individual current limiter built in to of each powertrain limits the total output current of that powertrain in an overload

condition. This allows flexible power distribution of the outputs of each powertrain. All outputs can either be connected in series or

in parallel; see

Electrical Output Data.

An auxiliary converter provides the bias voltages for the primary and secondary referenced control logic and auxiliary circuits. The

converter is only enabled, if the input voltage is within the operating voltage range and above the programmable undervoltage

lockout threshold (PUL) – such limiting the input current dependent on the nominal battery voltage.

All output are equipped with a suppressor diode and an independent monitor sensing the output voltage of the main output. In the

case of an overvoltage, it influences the control logic respectively.

The temperature is monitored and induces the converter to disable the outputs. After the temperature has dropped, the converter

automatically resumes.
