2 DESCRIPTION
The HTR28 Series of DC/DC converters offer up to 30 watts of output power with high
reliability. The converters are packaged in hermetically sealed metal cases, making them ideal for
use in aviation, aerospace and other high reliability applications.
The HTR 28 series of converters use a single ended, pulse width modulated and transformer
magnetic feedback topology design. The operating principle is that the sampling signal of output
voltage , coupled by the opto-coupler, works together with the sampling signal of input loop
current to regulate the pulse width of the controller. The double close loop control create constant
voltage output and short circuit protection.
Thick film hybrid techniques provide the HTR 28 Series of converters with reliability levels and
optimum miniaturazation.The design and manufacturing process of HTR 28 Series of converters
are in compliance with General Standards of Hybrid Integrated Circuits and detailed standards of
manufacturing. Connected to a HFD-CE03 filter, the HTR 28 Series of converters can achieve
better electromagnetic compatibility(EMC) performance.
