Energy consumption analysis of constant voltage and constant current operations in capacitive deionization
a b s t r a c t a r t i c l e i n f o Article history: Received 2 June 2016 Received in revised form 9 August 2016 Accepted 15 September 2016 Available online xxxx We report our studies to compare energy consumption of a CDI cell in constant voltage (CV) and constant current (CC) operations, with a focus on understanding the underlying physics of consumption patterns. The comparison is conducte...
متن کاملEnergy breakdown in capacitive deionization.
We explored the energy loss mechanisms in capacitive deionization (CDI). We hypothesize that resistive and parasitic losses are two main sources of energy losses. We measured contribution from each loss mechanism in water desalination with constant current (CC) charge/discharge cycling. Resistive energy loss is expected to dominate in high current charging cases, as it increases approximately l...
متن کاملConstant Current versus Constant Voltage Subthalamic Nucleus Deep Brain Stimulation in Parkinson's Disease.
Background: Subthalamic nucleus (STN) deep brain stimulation (DBS) is an established therapy for advanced Parkinson's disease (PD). Motor efficacy and safety have been established for constant voltage (CV) devices and more recently for constant current (CC) devices. CC devices adjust output voltage to provide CC stimulation irrespective of impedance fluctuation, while the current applied by CV ...
متن کاملA constant-voltage and constant-current stimulus isolation unit.
When action potentials from a stimulated biological preparation are recorded i t is essential to isolate the stimulus resistively and capacitively from the ground in order to minimize stimulation artifacts. Such isolation can be achieved by using a transformer of special low-capacitance construction in the output of a stimulus generator (Donaldson 1958). The most widely used arrangement for the...
متن کاملMeasurement of electrogenic-pump current in Aplysia neurones with constant-current and constant-voltage techniques.
1. The responses of the abdominal and pleural giant cells to warming and cooling were studied using constant-current and constant-voltage techniques. 2. The potential change upon warming from about 7 degrees C to 22 degrees C was reversed by application of maintained inward current. The reversal potential was -77 +/- 12 mV. 3. The membrane conductance increased with warming, but was not affecte...
