C 05/11/16 Page 10 Input: 230-400 V Output: 13.6 V Current: 45 A Package: EXTENDED Eighth-brick Applications Section Output Current Output Voltage 0V Time Time Output Current Output Voltage 0V PROTECTION FEATURES Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled “Input System Instability”. The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical Turn- On Voltage Threshold value (listed on the specification page) before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off. Also see Figure E. Input Over-Voltage Shutdown: The converter also has a two stage over-voltage feature that limits the converter's duty cycle for 100 ms before shutdown and a higher second level with no delay before shutdown if the input voltage is too high (See the Input Over-Voltage Shutdown section in the Electrical Characteristics Table for specific voltage levels). It also has a hysteresis and time delay to ensure proper operation. Output Current Limit: The output of the BusQor module is electronically protected against output overloads. When an overload current greater than the “DC Current-Limit Inception” specification is drawn from the output, the output shuts down to zero volt in a period of 1 ms typical (see Figure C). The shutdown period lasts for a typical period of 250 ms (Figure D) after which the BusQor tries to power up again (10 ms). If the overload persists, the output voltage will go through repeated cycles of shutdown and restart with a duty cycle of 4% (On) and 96% (Off) respectively. The BusQor module returns (auto resetting) to normal operation once the overload is removed. The BusQor is designed to survive in this mode indefinitely without damage and without human intervention. Output Short Circuit Protection: When the output of the BusQor module is shorted, a peak current of typically 70 A will flow into the short circuit for a period not greater than 1 ms (typically 200 uS). The output of the BusQor will shutdown to zero for ~ 250 mS (Figure D). At the end of the shutdown period the BusQor module tries to power up again. If the short circuit persists, the output voltage will go through repeated cycles of shutdown and restart with a duty cycle of 4% (On) and 96% (Off) respectively. The BusQor module returns (auto resetting) to normal operation once the short circuit is removed. The BusQor is designed to survive in this mode indefinitely without damage and without human intervention. In the Auto resetting mode, also referred to as “Hiccup” mode, the power drawn from the 385 V input is about ~10 Watts, most of which is dissipated into the external fault. It is important that copper traces and pads from the output circuit be designed to withstand the short term peaks, although the average current into the fault may be as low as 0.04 A typical. See Figure 17 for appropriate waveform. Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the Over-Temperature Shutdown value. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the Over-Temperature Shutdown Restart Hysteresis value.
