Patent ID: 7109608

Claim:
A smooth transition switch, comprising: a switch having at least one control input, a first signal input, a second signal input and at least one output; and at least one loop operably connected to said first signal input and said output, wherein said loop comprises: a first summing junction having a plurality of inputs and at least one output operably connected to said first signal input of said switch; a forward-loop compensator operably connected between said at least one output of said summing junction and said first signal input of said switch, wherein said forward-loop compensator is a simple proportional-integrate compensator; another summing junction having a first input operably connected to an output of said forward-loop compensator and a second input operably connected to said output of said switch; a feedback compensator operably connected between an output of said another summing junction and one of said inputs of said first summing junction; and a second loop operably connected to said second signal input and said output of said switch, wherein said forward-loop compensator is a signal processor, whereby said forward-loop compensator processes an error signal using an equation with transfer function C(s)=(b 1 *s+b 0 )/(a 1 *s+1), where at, b 0 and b 1 are constant coefficients and s is said control input; and said feedback compensator is a high gain compensator.
