《联系人；欧先生》 从工业领域到建筑工程，简单易用的开关模式电源非常常见。直流电压随后被缓冲至电池，成为随时可用的安全电力供给。事实如此简单吗？ 工频电源工作总是离不开变压器。输出的直流电，不管是调节的还是未调节的，都是首先在次级产生的。相比之下，开关电源是首先在初级进行整流，然后产生的直流电压被分割为高频，并通过一个小的高频变压器被传送到次级（图2）。开关电源允许宽范围的输入，还允许负载电流在0-100%的额定范围内连续工作。
图2: 无输入滤波器的开关电源原理图 在思考开关电源的输入电路原理时，首先注意到的就是整流器。如果输入不是交流电，而是直流电，将会发生什么？假设所有模块都能“准确”运行，那么几乎所有开关电源都可以直流电或者交流电输入。然而，当发生故障，一台不适用于直流电输入的开关电源，很有可能导致火灾，因为处理高压直流电比起处理交流电要危险得多。 RELIANCE ELECTRIC AUXILIARY CONTACT KIT K-607 K607 NEWAB RELIANCE ELECTRIC 500 HP AC DRIVE 608 AMPS 480 V #1 RELIANCE ELECTRIC TACH CONTROL BOARD 0-54355 reliance electric Variable Frequency Drive VTAC 15hp Reliance Electric HR2000 BLA-04 AC Servo drive 3RA2001 Reliance Electric HR2000 BLA-08 AC Servo drive 3RA2002 RELIANCE ELECTRIC (437162) PLC MODULE NIB RELIANCE ELECTRIC (437162 -R) PLC MODULE NIB Reliance Electric Remote I/O Interface 45C37A Reliance Electric 9 Slot Rack # 45C918 RELIANCE ELECTRIC 14C229 Master Isolated Ref Receiver RELIANCE ELECTRIC (437162 -X) PLC MODULE NIB Reliance Electric 0-52850 IRFA Drive Card New RELIANCE ELECTRIC 2GU41005 AC VS DRIVE GP-2000 5 HP Reliance Electric Induction AC Servo VZ3000 UVZ3202 OPC RELIANCE ELECTRIC 14C228 FIELD SUPPLY KIT NIB Reliance Electric Shark Programmer # 45C951 RELIANCE ELECTRIC 2DB2005 AC DRIVE 2DB2005 Reliance Electric 109081-102-W Card 109081102W NEW RELIANCE ELECTRIC 610266-29R MAXPAK III FIELD SUPPLY Reliance Electric Drive Board 8042510B 804.25.10B Reliance Electric Drive Controller 57406 Reliance Electric 8K Memory # 45C270 0702-03-015 ELECTRO-CRAFT E702 RELIANCE ELECTRIC MOTOR NEW RELIANCE ELECTRIC 0-52860-2 VSAC INVERTER ANALOG Reliance Electric 410403-24AWL Thyristor 41040324AWL RELIANCE ELECTRIC POWER SUPPLY MODULE 0-51903-A Reliance Electric 0-52712 115VAC Output Module 31C60A reliance electric 2-hp motor drive 460-v 60hz ac new BOX 8 RELIANCE ELECTRIC MOTOR BRUSH 404844-AU 404844AU Reliance Electric Drive Board 8041510A 804.15.10A LOT OF 4 RELIANCE ELECTRIC RESISTOR 63481XZA 8526 NEW Reliance Electric A40 Control Processor 45C410A 45C410 Reliance Electric Remote I/O Processor # 45C201 LNC Reliance Electric 4RC033 Encoder Cable NEW RELIANCE ELECTRIC 57410 ISOLATED ANALOG OUTPUT DCS MDL Reliance Electric 45C-201C/45C201?C I/O Processor RELIANCE ELECTRIC 1AC2003 AC VS DRIVE 3HP 3PHASE Reliance Electric 6 Slot Rack # 45C913 Reliance Electric 405919-43AW Diode 40591943AW NEW Reliance Electric Minipak Plus 14C13 5HP AC Drive Reliance Electric Shark Prog.
