Power supply apparatuses and power supply operational methods are provided. According to one aspect, a power supply apparatuses includes a power node, an electrochemical device configured to store electrical energy, a switch including a control node and the switch is adapted to electrically couple the electrochemical device with the power node in a conducting state and to substantially electrically isolate the electromechanical device and the power node in a nonconducting state, a controller configured to output a first control signal to control the operation of the switch between the conducting state and the nonconducting state, a controller configured to output a first control signal to control the operation of the switch between the conducting state and the nonconducting state and circuitry coupled with the controller and the control node and configured to receive electrical energy at a first voltage magnitude, to increase the electrical energy to a second voltage magnitude greater than the first voltage magnitude to provide a second control signal, and to output the control signal of the second voltage magnitude to the switch. |
