La puissance dissipée par les transistors si U de sortie est de 13,8 V et I de 30 A. P dissipée = 20 V – 13,8 X 30 = 186 Watts. Si I = 20 A. 20 V – 13,8 X 20 = 124 Watts. Pour 30 ampères, les deux BUV 21 vont demander au TIP 32 pour leur courant base-émetteur un courant IC de 3 ampères. Le TIP, quant à lui, demandera au 2SC 945 un ...
DIY LiFePO4 battery bank not charging above 13.6V
MOST LFP charging occurs below 13.8V. The increase to absorption voltage is very fast and occurs at the end. The 5.27A is going into your battery adding to the charge. ... You won''t hit 13.6V until you''re about 90-95% charged due to your extremely low charge current. Last edited: Sep 1, 2022. S. sduser New Member. Joined Jun 20, 2020 Messages ...

13.8V 80A Linear PS circuit design analysis for Ham Radio Use
My objective is to design and build a very high quality, very safe, very stable 13.8v Linear DC Power Supply that can sustain up to 80 Amps at a 50% to 75% duty cycle, and 60 Amps full duty-cycle. At this stage, I''ve pieced together a design based on old schematics found while cruising the web that makes use of the LM723 voltage regulator. I ...
How to convert a HP HSTNS-PL18 psu to 13.8V ?
Hi Guys, I''ve picked up a few of these PSU''s and have done the ''short 100ohm resister'' to get the output up to 13.8V. However, I have found on the two done so far that they go unstable (loud buzzing noise and a pronounced ripple on the output at around 1.3kHz) when the load goes above around 10Amps when set to 13.8V.
13.8V 2A Power Supply using LM338
If the connection between R2 and R3 is grounded using the S1a switch, then Q1 conducts and the output voltage is 13V (Zener D5 voltage). If the switch is on the other position Q1 is on cutoff region and the output voltage is 8,8V. LEDs D1 and D2 indicate if we have 13V or 8.8V on the output. Photos. PCB Photos. Video
