A power management method for generating a positive supply voltage of the secondary coil of a transcutaneous magnetic bond, and storing said positive supply voltage through a capacitor to feed an implanted stimulator channel, the channel comprising a current dissipator by that the stimulation current is forced to pass through a pair of electrodes, said pair of electrodes including their coupling capacitors, if incorporated, switches by which said pair of electrodes are selected and connected between said supply voltage positive and said current sink and tissue located between said pair of electrodes； - wherein, said positive supply voltage is generated by rectifying the alternating voltage of said secondary coil by closing or opening a solid state switch between said secondary coil and said capacitor at said times during the positive half of each alternate cycle that the voltage of said current dissipator is regulated within a rippling band just above the minimum level necessary by said current dissipator to maintain the demanded stimulation current； - wherein, said switch closes at the moment when the alternating voltage of said secondary coil crosses above said positive supply voltage if, and only if, the voltage of said current dissipator is less positive than a voltage positive reference at that time； - wherein, said switch is opened at the moment when the voltage of said current dissipator crosses above said positive reference voltage if the alternating voltage of said secondary coil is more positive than said positive supply voltage in that moment； - wherein, said switch opens at the moment in which the voltage of said secondary coil crosses below said positive supply voltage if the voltage in said current dissipator is less positive than said positive reference voltage at that time ； - wherein, the width of said undulating band can be made arbitrarily narrow by raising the capacity of said capacitor； and - wherein, the lower limit of said undulating band can
