The operation of this regulator topology has two distinct time periods. The first one occurs when the series switch is on, the input voltage is connected to the input of the inductor. The output of the inductor is the output voltage, and the rectifier (or catch diode) is reverse biased. ...
aUPSis that the DVR only supplies the part of the waveform that has been reduced due to the voltage sag, not the whole waveform. In addition, DVRs generally cannot operate during interruptions.Fig. 6.20shows a schematic of a DVR. As can be seen, the basic DVR consists of an injection/...
Rectifier and input filter iii) High-frequency chopper iv) High-frequency transformer v) Output voltage control circuit In general, an SMPS initially converts the ac source voltage into a dc voltage through a rectifier and an input filter. Then a chopper “chops up” the dc voltage, so that...
A power supply 202 which includes a rectifier input circuit MCR1 which provides either half wave or full wave rectified electrical current at an instantaneous voltage value to the input terminal of a controlled switch MQ3 is taught. The controlled switch is controlled by the combination of a ...

This discussion so far has assumed the regulator is in the continuous mode of operation, defined by the fact that the inductor current never goes to zero. If, however, the output load current is decreased, there comes a point where the inductor current will go to zero between cycles, and ...
However, the shunt regulator can be damaged if the voltage across the isolation becomes too high during an ESD event. The weakest point in the isolation is usually the optical-isolator leads. Once the optical-isolator gap is breached, the easiest path for ESD discharge will be though the ...
This EVM implements the 48- V to 1-V converter as a single-stage hard-switched half-bridge with current-doubler rectifier. This topology efficiently supports a high step-down ratio while providing significant output current and fast transient response. The TPS53632G controller uses a D-CAP+ ...
