A possibility that.
Once there is switch self breakdown or capacitor breakdown during the charging process in current existing small-scale driving source device
Failure, since Fault loop impedance is lower suddenly, charging current be increased dramatically, and charge power supply is past safely in order to protect itself device
Protection operation is automatically powered off toward will do it, this means that this charging process fails.Encounter problems, most common method
Charging operations are re-started after exactly charging system is resetted.Certainly, for certain permanent events for being unable to auto restore facility
Barrier, then can just re-start charging operations after needing to overhaul failure.For driving for source device on a small scale, due to opening
It closes and capacitors count is relatively fewer, the chance for occurring above-mentioned failure under same probability of malfunction is also less.But for advising greatly

Extensive Linear transformer driver (Linear Transformer Driver, LTD) device generally comprises quantity
Huge (~104Even 105) switch and capacitor, very likely occur individual or partial switch self breakdown during the charging process
Or capacitor insulation punch-through.Since the basic discharge cell impedance of failure can reduce suddenly, lead to the fault discharge
LTD module charging current where unit increased dramatically, and the charging current of remaining module will strongly reduce, so that greatly
The charging process of scale driving source device can not continue, it is meant that the charging process of whole device fails.If Trouble ticket
The also lasting charging of member, then being easy to cause the capacitor of the unit to explode because it concentrates consumption rechargeable energy.
