Abstract: There are disclosed herein various implementations of a connect/disconnect module for use with a battery pack. The connect/disconnect module includes a charge/discharge current path including multiple transistors having a first safe operating area (SOA), and a pre-charge current path coupled across the charge/discharge current path. The pre-charge current path includes multiple transistors having a second SOA that is significantly greater than the first SOA.

Abstract: In one embodiment, a power converter system includes an input terminal for an input voltage. A transformer, coupled to the input terminal, has a primary winding and a secondary winding. An output terminal is coupled to the secondary winding. Power is delivered to a load of the power converter system at the output terminal. A first control module, coupled through a relay to a tap terminal to the primary winding of the transformer, operates the power converter system if a magnitude of the input voltage is within a low voltage range. A second control module, coupled at an end terminal of the primary winding of the transformer, operates the power converter system if a magnitude of the input voltage is within a high voltage range.
