Abstract:
1. A functional electrical stimulation system comprising: a primary power; a boost module connected with the primary power, and is configured to raise an output voltage of the primary power to a first preset voltage; an energy storage module connected with the boost module, and is configured to store electrical energy of the first preset voltage; and an electrical stimulation output channel connected with the energy storage module, and is configured to convert the electrical energy stored in the energy storage module to an electrical stimulation pulse and apply the electrical stimulation pulse to a diseased part of a user; wherein the boost module comprises a timer, a voltage-regulator diode and n DC chopper circuits connected in series; the timer is configured to generate control pulses to drive the n DC chopper circuits connected in series so as to increase the output voltage to the first preset voltage in a multi-stage mode; an output of a last stage DC chopper circuit is connected to the energy storage module via a negative electrode of the voltage-regulator diode, where n≧1.
