1. A compressor system comprising:
- a compressor;
an electric motor drivingly connected to said compressor;
a source of electrical power;
a control system disposed between said source of electrical power and said electric motor, said control system operable to provide transfer power from said source of electrical power to said electric motor, said control system including a jumper movable between a first position when said source of electrical power is an alternating current power source and a second position when said source of electrical power is a direct current power source, said jumper controlling the power input to said control system from said source of electrical power.

Abstract
A fuel gas compression system includes a system which operates on direct current, a system which operates on alternating current and a system which is capable of operating on either direct current or alternating current. In the system that operates on either direct current or alternating current, a jumper is provided which is placed in the circuit when an alternating current is provided. When a direct current is provided, the jumper is removed from the circuit.
