Voltage Regulation: Ideas for Building Circuit

Click For Summary

Discussion Overview

The discussion revolves around designing a circuit to convert a wide range of input DC voltages (90-270 volts) to specific output voltages (either 88 volts or 112 volts). The focus includes exploring different methods for voltage regulation, such as buck converters and voltage regulators, while considering efficiency and component minimization.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using a buck converter for its efficiency but notes difficulty in finding one that accommodates the specified input voltage range.
  • Another participant raises a question about whether the voltages are AC or DC.
  • A participant clarifies that the voltages are DC and mentions the intention to use a rectifier circuit for conversion.
  • There is a suggestion to consider stepping down the input voltage to a lower range (9-27 V DC) before using a voltage regulator to achieve the desired output voltage.
  • One participant inquires about the desired output power for the application.
  • The original poster elaborates on the need for versatility in the design to accommodate different voltage standards in various countries, specifying the input and output voltage requirements more clearly.

Areas of Agreement / Disagreement

Participants express various ideas and methods for achieving the voltage conversion, but no consensus has been reached on the best approach or specific components to use. Multiple competing views remain regarding the design strategy.

Contextual Notes

Participants have not fully resolved the implications of using different voltage regulation methods, and there are uncertainties regarding the efficiency and practicality of the proposed solutions. The discussion includes assumptions about the input voltage range and the nature of the application.

Good day all!

I am new to this forum however i hear its great and full of good engineers. I want to convert 90-270 volts into either 88 volts or 112. I was thinking about a buck converter due to the efficiency however i cannot find one that can take my vin min and vin max. Then i though of a voltage regulator however i cannot find one that will give me my vin max. I also know that regulators that are built with resistors will lose lots of power due to heat dissipation and the voltage drop across the resistor may vary if voltage isn't constant. Please anyone give me some ideas on what i can do to build this circuit using as least components as possible. Thanks (PS this is not homework)

Are those AC or DC voltages?
 
Dc voltages ill convert the ac to dc by using a rectifier circuit
 
Can't you just go directly to the final voltage? What is the 90-270?
 
What output power are you looking to get?
 
okay I am sorry to everyone for not being clear enough in my 1st post and i thank everyone for their responses. I want the application to have an input range span on vin min 90v DC and vin max 270V DC. This is because i want my application to be diverse. If it were to be connected in another country that doesn't use our 120V 60hz system. I want to be able to step down that 90-270V to 88V for one application of the design or the 90-111 step up to the 112 desired or from 113-270V step down to 112v desired. The system will only pull what is needed...just looking to find components to help put my idea together
 
i don't know for sure, but can you step down your input voltage to a value say 9-27 V DC and then use the voltage regulator and then step up to your desired value?
