         Correcting my previous post, 
    the voltage charging period  of C6 is also 30 uS,to be more accurate, both with 26 uS…

       In the real circuit the period of L1 current is 30 uS and the voltage charging period of C6 is 15 uS.

       I excluded the transformer but nothing
    changed. 
    The transformer does not affect the
    charging time of C6, as it is blocked by D6.

    Hi Maurone,

    Yes, it was measured with a HITACH
    Oscilloscope V-212 20MHz.

    D2-R2 is the M1 tON control and
    D1-R1 is the M1 tOFF control as well.

         My main and only goal here at this
    time is to clarify a technical dilemma ( LTSpice IV x actual circuit)
    occurred during the implementation of a simple circuit in which the
    results from LTSpice and actual circuit were significantly different
    and I would like to know what could be wrong so that I can
    effectively put into practice what is actually being simulated by
    Spice.

    As mentioned before, it is a
    very simple circuit in which C6 charges up through L1 and is
    discharged through L2. The problem is that the charging time in C6 is
    60 uS Spice simulator (The time that I need ) and about 15 uS in
    actual circuit. So the problema is either Spice or is the circuit.
    Which one is right or wrong ?. I’m sure this question will be solved
    here.

    Thanks.
