Abstract

Embodiments of the present invention disclose an apparatus including a power source and a plurality of electronic subsystems connected in parallel to the power source. Each of the plurality of electronic sub systems includes a circuit breaker, a transient-voltage-suppression (TVS) diode, and a load. The TVS diode is located downstream of the circuit breaker in each of the plurality of electronic systems.

Claims

1. An apparatus comprising:

a power source; and

a plurality of electronic subsystems connected in parallel to the power source;

wherein each of the plurality of electronic subsystems includes a circuit breaker, a transient-voltage-suppression (TVS) diode, and a load;

wherein the TVS diode is located downstream of the circuit breaker in each of the plurality of electronic subsystems;

wherein the load is located downstream of the circuit breaker and in parallel with the TVS diode in each of the plurality of electronic systems; and

wherein when a plurality of circuit breakers in multiple of the plurality of electronic system fails an inductive kickback is generated, wherein the inductive kickback is dissipated through another of the parallel connected electronic systems.
