  • Patent number: 8755903
    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.
