3 Description of surge protection DC DC converter
This series device is highly reliable and is featured with surge protection (80v, 1s) for surge protection
DC DC converter. Single ended, pulse width modulated and transformer magnetic feedback topology
design is used in this device. 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 loop control creates constant voltage output and short circuit protection.
Devices are produced by using thick film hybrid integration process, and metal package seali
ng. The design and manufacturing process of HTR 28 Series of converters are in compliance with
General Standards of Hybrid Integrated Circuits and detailed specification of manufacturing. Input
terminal connected to the accessory power supply filter can improve the electro-magnetic compati
bility of devices.
