    Technique behind the Charging and Inverting Function of an Inverter

    Hello ,
    I have an inverter,
    In which has a H-bridge connected to a low frequency Transformer (230volt /7.5 volt) .

    Here the Inverting function such as DC to AC (12volt Dc to 230 volt Ac) produce by using the above said H-Bridge and the Transformer .
    As well as the same H-Bridge and the transformer used to charge the Battery (230 volt ac approximately 14.5 dc).

    How the 12 volt battery charges by the 7.5 volt ,What techniqe behind it ?
    I Respect You

    Re: Technique behind the Charging and Inverting Function of an Inverter

    Hi,

    Is there a filter (coil) between H-bridge and transformer or between transformer and mains?

    Without SOME Kind of drawing, schematic, circuit description, it’s impossible to tell what you are talking about. 12 volts? 7.5 volts? 14.5 volts?

    Re: Technique behind the Charging and Inverting Function of an Inverter

    I once put a voltmeter on the charger for my lawnmower battery. It read 10 or 11 VDC. Yet it was able to charge a 12V battery. I wondered how this was possible? It took me a while to figure out that the waveform could be rectified AC. Thus its peaks went well over 12V. There was no need to smooth the waveform.

    Re: Technique behind the Charging and Inverting Function of an Inverter

    I find out the answer from the thread following
    https://www.edaboard.com/showthread....nstant-current

    It use the technique Boost converter .
    Vout = Vi/(1-D)

    So the my first post said about 7.5 volt which can be simply boosted up our desired value thanks

    you cannot use the same Tx to charge the battery without some sort of boost circuit to raise the output of the rectified low voltage winding ...

    It charges ,The Boost coil is the secondary of the Transformer ,That is the Tehniuqe
