0 `描述 This reference design uses the UCC3895 Phase-Shifted Full Bridge controller to implement a high efficiency, 120VAC input to 44Vdc up to 8A output. The power supply is set up to be constant voltage-constant current. The voltage and current are set by fixed resistor values and could be set by micro-processor in the actual product. The design is biased by a low-cost BJT Flyback using the UCC28720 PWM controller. 特性 120Vac input, 44Vdc @ 2-8A output >92% efficiency achieved @ 8A High-side Gate Drive Tranformers used for lowest cost implementation. Low-cost BJT flyback used for design bias Flexible setting of Voltage and Current levels by fixed resistor values or micro-processor in real design PMP9622 Assembly Drawing.pdf (270.31 KB, 下载次数: 8 ) PMP9622 BOM.pdf (148.15 KB, 下载次数: 3 ) PMP9622 Schematic.pdf (355.9 KB, 下载次数: 8 ) PMP9622 Test Results.pdf (354.42 KB, 下载次数: 4 ) tidc965.zip (598.74 KB, 下载次数: 3 ) ` 0
