This is why the term ‘coil’ is used in practice to mean an inductor. The core of the coils is often made of a magnetic material in order to increase the magnetic flux and therefore the inductance of the resulting inductor. The non-linear magnetic property of the core material can lead...
These developed converters have been demonstrated to achieve high voltage gain but at the cost of utilizing a high number of inductors and capacitors. Moreover, coupled inductors can result in leakage inductance, leading to a very high spike voltage across the MOSFET during the off-time. This ...

PROBLEM TO BE SOLVED: To provide a voltage-controlled oscillation circuit capable of preventing a current leak to shorten a time for stabilizing an oscillation frequency when turning on a power supply. T Yoshichika,高橋 佳周,O Tomoki,... 被引量: 0发表: 2008年 INDUCTANCE-SWITCHABLE DUAL-BAND ...
There is a parasitic Effective Series Inductance (ESL), and a parasitic Effective Series Resistance (ESR). Both ESL and ESR decrease the capacitor’s performance at high frequency. Figure 1. External Capacitor Model There exist several elaborate models of a real capacitor. In Figure 1, above, ...
The suggested control approach takes the switched nature of the converter into account in both the system model and the control objective. This has two main advantages. First, it removes the need for the low-pass filters which are conventionally applied to the state measurements to attenuate the...
In addition to their compactness and higher power density capability, ABB's dry capacitors for DC applications have many more advantages such as self-healing, superior end-of-life performance and low inductance, making them extremely suitable for very demanding applications. 4 110 kV passive ...
When measurements and extraction are done properly, we can expect that at low frequency, where the contribution from reactive components (capacitance and inductances) is small, the model will be correct. The situation is different when the device is affected by dispersive phenomena [23,28–36],...

One needs to also minimize trace lengths to reduce the trace inductance. To minimize this error the reference must be placed very close to the VREF pin of the ADC. If the reference has VOUT sense pin then problem of trace resistance can be eliminated by connecting output sense pin to ...
