boost converter

Hello all, I'm designing my first half bridge boost converter and I've got these two problems: These transients that appear no matter what simulation model of MOSFET I use. I've got these massive spikes. They even appear when I insert larger diodes onto the MOSFETs. Is this an artifact of the...

In the following, you can see three images. You can see my solution as well as the correct answer. Can you tell me how and from where the highlighted factor come?

Hello everybody! I am trying to design a boost converter using TPS61088 IC. I used the design tool from Texas Instruments to get the values for the components. Here is the circuit: The voltage output seems to be fine. I get 5.1V output. The circuit it's designed to be supposed to handle a...

I am experiencing a challenge with the design of a DCDC Boost converter that is intended for gasoline direct injection control. This DCDC converter is configured to generate 65V from a 12V supply, utilizing the NXP PT2001 controller (the MC33816 is quite similar, as the PT2001 manual is...

With Vin=12V and a 60% duty cycle, I was expecting a 30V output. But Instead I got a Vout=27V. I thought it was because of the diode, but its forward voltage drop is only 0.2V. So I tweaked everything and I noticed I had to make Rload=80 to get a 30V output. Why can't Vout=30V when Rload=50?

I am not sure what is wrong with my boost converter. Normally, at 0.5 duty cycle, Vout should be twice Vin. But somehow it is much higher. For my switch, Vto=4.99V (Is Vto equal to Vthreshold? As in switch turned on when Vgs>Vthreshold). With gate voltage varying between 0 and 24V, Vout would be...

I have an assignment where I have to make a boost converter. this is the schematic of the circuit I have; the problem is that the boost converter can increase the voltage if the load used is a 2.5 watt incandescent lamp (can go up to 12 V), while if I use a resistor (100, 220, 470 ohms etc.)...

Hello guys. I am working on a project that aims to implement an MPPT controller for a small wind turbine and evaluate the performance gain compared to having no MPPT. I have built a wind turbine prototype using pvc pipes for rotor blades, 3d-printed rotor hub and nacelle, and a metal pole tower...

Hello all, Disclosure, I am an electrical engineer but I deal with designing power system for construction projects. I decided to go back for Masters in Power Electronics. I'm rusty with DC circuits. My homework is the same as a previous thread...

Hi, We have designed a 50kW 3 level boost converter for our fuel cell EV application with liquid cooling. It is an IP65 module of dimensions 400mm x 300mm x 85mm. Its internal ambient temperature is rising very high. There is no specific component that emitting abnormal heat it seams, but we...

Howdy! I'm trying to design a boost buck convertor from a 3D printer power module and I am using Multisim to simulate it before starting but I think I'm having issues with the biasing. (EE student noob here so bear with me!) My requirements are Vin 12V-30A Vout 0-50V (inverted) For the PWM I...

Hello folks, I'm just new to the forum. I'm looking for help using a 400w 15A DC-DC step up boost converter 10-60 volts. I watch many youtube video of people who can set voltage and amperage with that. But I can't do the same. Here is my project : I want to power a COB LED 30-34v 200w. I have...

I have a boost converter that i want to use to step up the voltage from 12v to 15v. (https://surplustronics.co.nz/products/7589-step-up-power-module-dc-dc-boost-converter) my power supply is 12v 12.5A, and the maximum input current is 4A. to solve this, I have a 1.5ohm resistor in parallel with...

I'm pretty newbie. i designed a boost converter as hobby and need some help about that. not sure if it will work. how can i fix or improve the circuit. i aimed 5 Vin and 15V 10A max out and use 555 for generate pwm signal for mosfets. But i know 555 can generate max %50 duty cycle and it means i...

1. I use a medical therapy device that needs 72 volt ac input. 2. Need to drive the medical device from a 5 volt dc Powerbank for mobiles that are readily available in markets 3. For that, I need to somehow step up the powerbank output from 5vdc to 72volt (either ac or dc) 4. The max load...

I built a boost converter to boost voltage from 200V dc to 400V dc. Power rating is 5kw, I added a PID to regulate the voltage. The problem is, when going from light load to heavy load, output voltage causes overshoot. After going to heavy load, further load addition has no problems. For ex...

Hi folks, I think what I have is a fairly simple question, yet I've spent so much time Googling, that I've completely lost track of what is what. I'm looking for an affordable voltage regulator to power an ESP32 from a number of AA or AAA batteries. I have bought a pair of these (Dutch...

Hi its a boost converter circuit. its mean it make increase applying voltage on the output . I am applying 201.6 volt and I should see approximately 650 volt on the output. But I have a problem about capacitor. When I use basic capacitor, I realised that my capacitor is not working well...

Hello, I have an inverting boost converter which is giving me some difficulty. It can be found on pages 1 and 3 of the PDF attached (the non inverting works fine). This inverting boost converter should (and has in prototype) produced -100V - 0V without any difficulty. All control signals are...

Hello, I have been making circuits as a hobby for 2 years now mainly focusing on trying to make a coil gun, and tried and failed 7 times now, and I am in desperate need of help with the circuit, if you see anything wrong with my diagram please respond as soon as possible. I bought most of the...
