Abstract: A functional electrical stimulation system having a boost module to raise an output voltage of a primary power to a first preset voltage, an energy storage module, connected to the boost module, configured to store electrical energy of the first preset voltage, a central control unit configured to generate data packets of electrical stimulation parameters, and an electrical stimulation output channel, connected to the energy storage module, configured to receive the data packets of electrical stimulation parameters, analyze the electrical stimulation parameters from the data packets, convert electrical energy stored in the energy storage module to an electrical stimulation pulse corresponding to the electrical stimulation parameters and apply the electrical stimulation pulse to a part of a user.

Abstract: The present invention discloses a functional electrical stimulation system comprising a primary power, a boost module, an energy storage section, an output control relay, an automatic discharge circuit, a foot/hand controlled switch, a current detection chip and a current limiting fuse. The boost module comprises n DC chopper circuits connected in series, and outputs a high voltage of 100-200V. According to an enable signal and a current detection signal, the output control relay disables/enables the DC boost module. The automatic discharge circuit discharges capacitance of the energy storage section automatically when the relay turns off the power input. The Foot/hand controlled switch, the current detection chip and the current limiting fuse form a triple accident protection circuit. The functional electrical stimulation system maximizes the intensity of electrical stimulation within the range that the human body can withstand.
