Generally in AC we consider voltage, frequency and phase
sequence for parallel operation ... Can we parallel two DC
battery chargers? If yes, then what precaution to be taken
when we parallel two DC power?

Answer Posted / pankaj verma

Main criteria for parallel connection is :
1. Both chargers should be connected in the same polarity.
2. Voltage of both the chargers should be same.
3. chargers should have identical specification.
Practically chargers are never used in parallel, they are
just momentarily paralleled in order to shift load of each
other so that maintenance work on each one can be carried out.
