## help - Varistor selection

hello dear forum, I have chosen a varistor for my inverter bypass capacitor protection my circuit is an inverter for high frequency ( 28 KHz ) output it operates from the 220 VAC mains so the voltage across bypass caps are about 310 V + %10 the inverter power is about 3 KW my question ; is my varistor (...)

## How to make Inverter Transformer

How to make 220-240VAC (50Hz) to 12vdc transformer. Please tell me all the specifications i.e. no. of turns in primary and secondary, the dimensions of the core (if relevant!! current dimesions are given below), diameter of the winding coil etc.. it will be a center tapped transformer with 2 primary winding for switching purpose.. and 1 secondary w

## inverter theory - how can I bring the inveter to resonance ?

hello dear forum, this below circuit is the schematic of an ultrasonic inverter 129223 I want bring the circuit to resonance by playing with the value of inductance between output transformer and the piezo element my question is ; if I display the current and voltage at the 220 VAC input with the osciloscope -

## Ebay 500Watt DCDC boost inverter 12 to 220/380 volt.

Dear Reader, I have found at ebay a Boost inverter module called "500W-DC-12V-To-AC-18V-160V-220V-380V-inverter-1-5A-Pre-amplifier-Boost-Converter" I'm interested in using this DCDC module but would like to know if

## Problem with 12 to 220 inverter

Hello , i build 12 to 220 inverter based on 555 Timer : 125629 I use a 9.5 v ac transformer and a 6FM 12V battery , but the output of the inverter give 74V ac !!!!! 125630 125631 125632 i think that the problem is the trans

## 120 volt battery charger

AC input voltage 220 - 240 V Current rating 40 A maximum frequency 50 - 60 Hz batteries are lead acid , and power will be drawn from an inverter while charging batteries . One thing more can i use half wave rectifier and than filter it using capacitors to take an average value dc ?

## 12 to 220 modified inverter

I have built my 12 to 220 modified inverter (1000 watt). I use ATMEGA8 and IRF3205 in my design. I am sure about 220V and 50Hz on output. My design almost look like this. 107891 In addition to feedback signal. My problem is : this inverter Destroyed my three home fans (its driver board use triacs). 1078

## 12 V DC to 220 VAC inverter

I am trying to build my 900 VA inverter My problem is in charge battery phase, I don't use external rectifier diodes but I depend on body diode of mosfet transistor (IRF3205). In case of 220 V on primary, the secondary is 16 V but the maximum battery voltage was 12.2 V, and the charge current is 100 mA. What is the wrong ? 10

## Pure Sine Wave Inverter

I am working on pure sine wave inverter 22 V DC Input to 220 V, 50 Hz AC Output. Have generated SPWM signal using Atmega16. Testing Load: Resistive, may try with Inductive load too. Can someone recommend me which MOSFET and MOSFET DRIVER should i use for H-Bridge, and please give a explanation too why because i don't know how

## inverter 12vdc - 220 vac (problem)

Hello everyone, i have a problem with my inverter 12 vdc-220 vac (pure sine), that i use for to transform the fotovoltaic energy in to voltage for domestic use. the energy is stored in to some the batteries. we come to the problem. some days ago i realized that my inverter had an malfunction. when i turn on the main switch it not power (...)

## HELP:Generation 3 Phase sine Look-up Table

Hello I am using 6 channels of a timer to generate PWM waveforms at 16KHz These drive 6 MOSFETs. I have a sine table of 32 entries 0 25 49 73 96 118 139 159 177 193 208 220 231 239 245 249 250 249 245 239 231 220 208 193 177 159 139 118 96 73 49 25 I have a bridge inverter built as shown below R (...)

## Large currents in the input of a full bridge restifier

Hello everyone, I am designing an inverter, and I have a problem in the rectifier stage. I rectify the 220 VAC using a full bridge (and a capacitor), and then I'll use the rectified 300 VDC as the input of my inverter. The problem is that since my inverter has a relatively large load (5-10 A), I will have very high peak (...)

## technical issue about sine wave inverter

Modern TVs are usually specified for 90 to 260 V AC input as all use a switching power supply inside which can accept the complete input ACvoltage range. If your particular TV only is specified for 220 VAC, then a 110/220 V inverter should work, too. Only please make sure that the inverter does not generate overvoltage with (...)

## pic 16F877a sine wave inverter 12 dc to 220 ac

i see. but i'm not much of a programmer and the available programs is for 16f84 and others. don't know how to reprogram it for 16f877. the loader we have here is only for 16f877. we tried to search for 12vdc to 220ac inverter here, but only modified sine wave is only available, we have to order abroad to get a pure sine wave but our budget is only

## 600/800W 220~230v AC Inverter SMPS from 12v DC

ETD34 core area = .971cm2 and Aw=1.220cm2 as per my calculation it is around 265w at 50khz and 348 W at 100khz assuming current density is 4A/Sqmm this calculation is for Half and Full-bridge

## Making a 12-220 inverter, HV part with TL494

I'm learning how to make an inverter, and need help figuring out what is normal and what is not, and fixing the latter. The basic layout is - make 320V from 12V, using a high frequency, small size ferrite transformer, rectify the 320V, turn them into AC with a full bridge. It splits nicely into two parts, and i want to debug them separately.

hi vvarlord first of all , i will give u the overview of the inverter ,, 1) linear transformer based inverter now i will tell u in detail about this type -- LINEAR TRANSFORMER BASED inverter-- In this type of inverters ,,first of all 12vdc is converted into 12vac(square wave or modified sine wave or pure sine wave) (...)

## Need help for 200 watt power supply, Source is 12 volts DC

Is this for your vehicle? You may want to investigate something like raspberry pi, which can operate from 5v. Otherwise, I'd suggest that it is quite hard for someone new to electronics to develop a PC power supply that operates from 12V. There is the inverter option to take 12V and convert to 220 so that you can power a conventional 220V (...)
