Section 4. High Voltage and High Current Applications

Parasitic capacitance effects in step-up transformer design (13)

This chapter explores the causes of the large resonating current spikes on the leading edge of the switch current waveform. These anomalies are exacerbated in very high voltage designs.

High efficiency, high density, PolyPhase converters for high current applications (14)

This application note addresses the following questions. How much do I gain by using a PolyPhase architecture? How many phases do I need for my application? How do I design a PolyPhase converter? The design example of an LTC1629-based, 6-phase 90A power converter is presented. The mathematical equations and graphical curves for calculating the ripple currents ...
