A new dc-dc converter is presented to perform the precise regulation of multiple output voltages, which is composed of the cascade connection circuit of the improved forward type multiple-output converter and the step-down type single-output converters. In the conventional multiple-output converter using cross regulation, the steady-state errors in the cross regulated outputs cannot be made smaller...
An SCR DC to DC converter is described which will operate at an output of 275 kW and will supply current to electron storage ring magnets requiring 5 hr. stability of 50 ppm. The operation of this modified chopper is described and design equations are presented, along with the system control loop description.
A theoretical model of npvn power transistor turn-off transients oriented toward circuit analysis is presented. It predicts the collector voltage waveforms under constant collector and reverse base currents in closed-form expressions. In particular, a storage period, a voltage-rise period and their dependence on currents and device parameters are revealed. It also provides a conceptual one-dimensional...
