Take an example, where a battery is to supply two power electronic converters separately. If we switch the contacts of the battery from one converter to the other using two contactors, will it create a significant loss in the converter paths? How much will the efficiency get affected by this method (using contactors)?
What are the other problems that can arise, like the effect in control (due to the resistance or any other component of the contactor)?

Make sure that (1) the contactors haaveRC networks to absorb transients and (2) the system is proof against the condition of both contactors being open or closed (by some fault condition). For safety!
