The low loss pwrgate uses mosfet power transistors to switch the load between power sources with less then a 20 milivolt drop much smaller then similar systems that use schottky diodes.
Epic pwrgate is a 12 volt backup power system rated at 40 amperes continuous from either a power supply or a battery.
Gate driver add to the power dissipation losses.
Connect the communications equipment to the low loss pwrgate and enjoy knowing you now have full backup power.
P drv is the total gate drive loss divided to calculate the driver loss r ghi is turn on of the driver.
Connected equipment will instantly switch to battery during a power blackout or power supply failure.
System checkout when the power supply and battery are connected and the low loss pwrgate is powering a load a quick check out is as follows.
Calculation of power loss synchronous rectification type gate charge loss gate charge loss is a power loss ascribed to mosfet gate charging.
Connected equipment will instantly switch to battery during a power blackout or power supply failure.
It depends on the gate electric charge or the gate capacity of the high side mosfet and low side mosfet.
Simply turn on your equipment then unplug the power supply.
As shown by equation 6 gate drive losses do not all occur on the mosfet.
