Behavior of Bipolar and MOSFET transistors used in power stages of a controlled current amplifier
Radu Arsinte, Dorin Marius Petreuș · 2009
The paper presents a comparative analysis of power efficiency and speed for different solutions of driving inductive loads. The main application is a power stages in special CRT display systems, requiring high efficiency, low rise and fall times for the current (less than 1µs for full scale current variation - 2App). The paper analyzes a controlled (hybrid) main bridge topology, implemented both in Bipolar and MOS technologies for the final stages. The results for simulation of the theoretical and optimized circuits are presented.
