To simplify the circuit design and control complexity, a wireless charging system with switchable hybrid topology based on an integrated coil structure is proposed in this paper. Constant current (CC) constant voltage (CV) outputs under zero phase angle (ZPA) conditions can be achieved at fixed frequency by simply throwing compensation element receiver. Firstly, modeled using mutual coupling th...

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...

Primary-side regulation (PSR) scheme is widely applied in low power applications, such as cell phone chargers, network adapters, and LED drivers. However, the efficiency and standby power requirements have been improved to a high standard due to the new trends of DOE (Department Of Energy) Level VI and COC (Code Of Conduct specifications) V5. The major drawbacks of PSR include poor regulation d...

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 ...

Early leak current, i.e. for times similar to the time to peak of the transient current was measured in Myxieola giant axons in the presence of tetrodotoxin. The leak current-voltage relation rectifies, showing more current for strong depolarizing pulses than expected from symmetry around the holding potential. A satisfactory practical approximation for most leak corrections is constant resting...
