An inverter normally includes at least one inverter bridge, and such a bridge is normally composed of one upper switch and one lower switch. On each bridge, either the upper or the lower switch must be kept on; otherwise, one has YL(s)=0. Moreover, the source admittance YCS(s) is no...
The controller is configured to detect an over-current condition of an inductor current in the switching power converter using at least one non-inductor-current signal. In at least one embodiment, the switching power converter does not have a resistor or resistor network to sense the inductor ...
A DC-DC voltage converter has a pair of switching transistors to provide an output voltage and are alternately switched in a boost mode of operation responsive to control signals. An inductor is connected to the pair of switching transis... CONGZHONG HUANG,SICHENG CHEN,XUELIN WU 被引量: 4发...
7.56(c) the resonance current becomes zero when the resonance capacitor voltage reaches the peak value, and thereafter the resonance capacitor starts discharging while the inductor current is negative. Moreover, the resonance inductor current reaches its peak when the resonance capacitor voltage drops ...
Moreover, auxiliary sensing FETs are proposed to eliminate sharp transitions in the sensed high-side and low-side currents as the buck converter switches between the ON and OFF phases. Eliminating these sharp transitions enables the bandwidths of the current sensor's control loop and the nonlinear...

A constant-frequency current-mode-controlled boost converter circuit provides slope compensation of an inductor current, reduces reverse inductor current in light output load conditions, and reduces oscillation between a discontinuous cu... BZ Hai,L Jin,JW Yong - US 被引量: 2发表: 2013年 Evaluatio...
Things are very different in ac circuits because the current is always changing. The back-EMF always acts to retard the change in current whether the change is an increase or a decrease. The ability of the inductor to resist changes in current is measured in terms of its inductanceL. ...
Theoretically speaking, even if the current-limiting circuitry had responded immediately to the overcurrent condition, and if the intervening traces had truly negligible inductance, the switch may still take a little time before it really turns itself OFF. During this delay, if the inductor is satu...
