Weak current College】 【power technology glossary (1)】.


Specific term abbreviations or
The symbol definition A AC-DC suitable electronic equipment can operate on AC or DC currents.
Also: ac dc, ac/dc, ac-dcAC-DC converter AC-DC CONVERTER a AC go to DC devices, commonly referred to as offline converters, AC voltage is rectifier for DC, or include power factor correction, or other features.
Also: ac dc converters, ac/dc converter, ac-dc converter AC power good signal AC-OK SIGNAL that signal is used to indicate the 115/230Vac power input AC voltage of conduction and interrupts. Height measuring ALTITUDE TESTING aircraft or other aircraft of electronic equipment for certain functions and features. According to military standards MIL-STD-810, usually require a high level test. Environment temperature AMBIENT TEMPERATURE ambient temperature usually refers to the most relevant to the power supply still air temperature. Apparent power APPARENT POWER AC circuit power values. This power is equal to the valid values in the circuit (rms) current and valid value (rms) the product of voltage, calculate the power, regardless of the power factor. B ball grid array BALL GRID ARRAYBGA a universal standard for IC SMT attach method that is used for plate installed VI chip. Bandwidth BANDWIDTH determine a phenomenon of frequency range must be considered. Substrate BASEPLATE power module has a installation of the aluminum plate. With that the substrate temperature is the temperature of the module. The substrate should be added to the heat sink thermal surface. BELLCORE specifications of BELLCORE SPECIFICATION Bellcore communications industry standards. Bipolar Transistor TRANSISTOR using BI-POLAR minority carrier through PN principle of transistors, and voltage control devices (MOSFET), the transistor to current controller. Leakage resistance BLEEDER RESISTOR for capacitor discharge, in the circuit can access a leak resistance, in order to produce very small leakage current. Coil skeleton BOBBIN wire transformer or inductor coil brackets. The framework also allows the coil and core insulation. Multiplier converter module BOOSTER CONVERTER in drive/multiplier module composite structure, received the drive module is "charged" module. In composite structures, many multiplier module can only received a drive module. Breakdown voltage BREAKDOWN VOLTAGE in the role of the voltage, the electric insulation was destroyed, and with it creates larger leakage current, even arc light sparks. In the power system, votalge refers to the input to the output or input and output to the top of the chassis, AC or DC voltages. BRIDGE bridge converter CONVERTER bridge converter DC-DC converter's circuit structure. In power transformers at both ends of the bridge structure, with two or four only source switching devices. Bridge rectifier BRIDGE RECTIFIER diode with four bridge full-wave rectification circuit. Electricity demand is higher than BROWNOUT issued charge or distribution of electricity, in order to reduce the power consumption, power companies typically will reduce the voltage of the AC power rationing. Aging BURN-IN power products factory, in order to exclude components early failure and other potential impacts, and should normally be run under the rated load for a period of time, this process is called aging the product. Bus converter module BUS CONVERTER MODULEBCMVTM of one, with the transit bus architecture IBA applications. BCM from a pre-soundness of pressure DC sources transit bus bar voltage isolation, to the non-isolated load dian converter. BCM than traditional brick-IBCs superior. C Canada Standards Association CANADIAN STANDARDS ASSOCIATIONCSA expressly the power component of the standards and safety requirements. Capacitively coupled CAPACITIVE COUPLING between the two circuits through discrete capacitors or parasitic signal coupling capacitors. Center-tapped CENTER TAP in transformers or inductor point lead electrical connector, both ends are usually coil Center tap turns should be equivalent. C-level C-GRADE an industry standard, the c-class devices operating temperature not lower than-20 parallel C. Chassis mounting structure CHASSIS MOUNT CONFIGURATION of various modules or Exchange front-end circuit directly mounted on the chassis, called the chassis installation structure. COMMON-mode noise-MODE NOISE on the two conductors have a datum point equivalent of noise, typically refers to the AC power line and the noise of the Middle Earth. COMPAC Huai of DC input power, the power supply meets industrial and communication products for EMC filter and transient protection requirements. Constant current power SUPPLY CONSTANT-CURRENT POWER when the supply voltage, load, ambient temperature changes or output voltage change over time, the output current stable and constant power. Voltage power SUPPLY VOLTAGE CONSTANT-POWER when the supply voltage, load, ambient temperature changes or output current drift over time, the output voltage remains stable and constant power. Control circuit CONTROL CIRCUIT closed-loop system in a circuit. The circuit there is usually an error amplifier, a control system to adjust the State of the system. Converter CONVERTER using inductor and capacitor filter with high-frequency switching function, which converts the DC input voltage for different DC output voltage of the circuit.
