3. Description of HVTR28 Series High Reliability DC/DC Converters

HVTR28 series products are designed using single-end structure and PWM principle, as well as transformer magnetic reset technology and, are new generation 30W series defense DC DC converter developed through improvement. After being isolated and coupled through optic coupler isolation, the sampling signal of the output voltage of the product and the sampling signal of current in input circuit modulate the pulse width of the controller at the same time. Its double-circuit close-loop control makes the product have stable voltage output and short-circuit protection function. This series product is made by the thick-film hybrid integration process and is totally sealed in a metal case. Both the design and manufacture of the product satisfy the requirements of GJB2438A-2002 “General specification for hybrid integrated circuits” and specific specifications of the product. The connection of input into HFG-CE03 power filter can improve EMC performance of the product.
