Discussion Character
- Technical explanation
- Debate/contested
- Exploratory
Main Points Raised
- One participant seeks schematics for a voltage regulator that can control output voltage from a 320 Amp alternator, specifically for powering amplifiers that require up to 20VDC.
- Another participant corrects the original poster's description of the battery configuration, noting that the two 8V batteries are in series to achieve 16V, not parallel.
- Some participants discuss the challenges of building a regulator capable of handling high currents, suggesting the use of parallel power BJTs with series resistors to balance current distribution.
- A participant expresses uncertainty about the original poster's amplifier setup, questioning the power levels and the implications for the regulator's design.
- There is mention of a related thread that may provide additional insights or schematics.
- One participant shares a Wikipedia link on voltage regulators for background information, highlighting the bipolar follower arrangement as a potential solution.
- Another participant emphasizes the need for adequate heat dissipation in the regulator design due to the high power levels involved.
Areas of Agreement / Disagreement
Participants express varying levels of understanding and expertise regarding the construction of the voltage regulator, with some providing technical insights while others seek clarification. There is no consensus on the specific design or approach to take, and multiple viewpoints regarding the requirements and challenges remain present.
Contextual Notes
