Converters Definition and 40 Threads

I'm no Electrical Engineer. But I do have a lot of questions pertaining to Electrical theory. One topic as of late that has the cogs in my brain turning, are Converters. For instance, I work on Comfort Cooling and Heating Systems for a living, as of the last 3-4 years DC Inverter Heat Pumps...

Hi, I love physics since school, but after years I forgot a lot of what I studied. I hope this forum will help refresh my memory. Also I built a web converter application to convert different measurement units and this forum can be really helpful for me to promote it and keep improving it. Thanks

I have two capacitors in series across my bus. I have a some series resistors across the capacitors for voltage balancing. I would like to power some low voltage low voltage components tapping off of the voltage divider using that as the voltage supply. The bus voltage will be approximately 2...

Hello, I am looking for some softwares that can convert htlm files into pdf and join them. I know Adobe Reader can do this and there are online converters but I am looking for alternatives of Adobe and offline options. Can you please recommend one if you know any? Thank you.

Hi. This is my first post. Thanks to all who give it a look. I am working on an application that has very stringent power output requirements. There is a rechargeable battery that I am trying to manage through a bi-directional boost/buck converter as is typical of many modern-day electric...

Let K=2Lfs and Pin=Pout, Have, (Vin-Vo)/k D^2 Vin =Vo ^2/R (I am fine up to this part. I am equating input power to output power) V^2=D^2 + D^2 R/2 Vo Vin - R/k D ^2 Vin =0 (This is where the instructor takes over. Can’t figure out how he got to V^2. Where did that come from? Thought I was...

Hi! I was wondering if you can suggest any decent DC-DC step-up converter that would actually withstand 100W output? My intention is to convert 12V to 23-24V and feed it to 100W consumer. I got myself 150W step-up module that according to specs should withstand 150W or 6 Amp at output (when you...

Hi, I have a graduate level understanding of power electronics. The other day I decided I wanted to series the output of two DC Boost converters. I remembered the simple conceptual circuit of how they worked, and I jumped onto google to see if this could be done safely. What I read was that it...

In a circuit that I am building, I have a rectified DC of about 22V, and I want to regulate this down to say, around 8V to 10V. Previously, I thought of using a voltage regulator, LM7808, as discussed here, but I strongly believe that a potential drop of 22V - 10V = 12V would produce a lot of...

Hello Everyone, I am still trying to get my head around what a current to voltage converter (and vice versa) is. There is a section on my book, in the chapter about op amps, that discusses this topic. Apparently, a current signal is less susceptible to noise than a voltage signal... But what...

Say I have a disk spinning in a buoy. Let me say the spin axis is vertical to the flat surface of the buoy (or sea if there were no waves). Now along comes a wave (that will induce a "precession" of the disk/buoy. The axis of this precession is from "starboard to port." This would induce...

Why is chaos only more studied in dc-dc converters and not in other nonlinear circuits, such as, rectifiers?

Hi Guys, I have a question on the need for Digital to analog converters in Transmitters. To elaborate bit further: 1) Because of the advantages of the Digital signals, most go the signal processing in wireless communications is performed in baseband. But my question is: Since digital...

I have a ton of 1A buck converters, and have a 5A application in which i need to run. I do not want to order any new buck converters, because I already have so many 1A ones, and do not have money for any new ones. Each one can only handle 1A before it over heats. I was wondering if I could use...

I'm confused, how is it that DC-converters work with respect to KCL in terms of conservation of charge? When a boost/buck converter would output low/high current output than input? I_in =/ I_out I'm teaching myself the basics of circuits, understood KCL and KVL, but this point is confusing...

I'm upgrading a non-PFC (power factor corrected) offline power supply design to include PFC for European deployment. The total output power is less than 25W, and the two output windings are around 20V. I'm familiar with boost-flyback topologies for isolated PFC supplies, but that seems to...

Homework Statement The input bits 0 and 1 are represented by 0 volts and 5 volts respectively. The OP-AMP is ideal, but all the resistances and the 5 volts inputs have a tolerance o f ± 10%. The specification (rounded to the nearest multiple of 5%) for the tolerance of the DAC is?? In this...

(I am a big newbie when it comes to electrical circuits) So I am searching the Internet for how the Solar inverters work. Most schemes that I come across have an H-bridge with some sort of transistors. Now how I understand the transistors are controlled by an oscillator and bridge itself then...
