    DIY Power conditioner (for mains 230V)?

    Hi Nick, How’s your audio console PSU running these days? Is this the next stage of improvements? I am not an expert in filtering power but I thought I might add something. There is a jungle of filters out there called different names as; ground loop isolation transformer for hum reduction...

    gating signal for six MOSFETS or SCRS

    I don’t really see the point here. Why convert mains to 12VDC and back to mains for a motor instead of running the motor directly from mains???

    gating signal for six MOSFETS or SCRS

    A regular size car battery will not run a 1hp output motor for more than a few minutes. The battery will be destroyed after only a few cycles (charge/discharge) since a starter battery is not suitable for deep cycle use (deep discharge).

    gating signal for six MOSFETS or SCRS

    Hi, I think you should look at an IGBT inverter bridge for this. Perhaps it is possible with mosfets too but common thyristors should be avoided I believe. This can be controlled by a 12-puls system, much like the second half of a 3-phase motor AC-drive. It will not produce perfect sine wave...
