Stair Current Output Power Supply for Switching Magnet*
نویسندگان
چکیده
The switching magnet for beam distribution is served with Digital Signal Processor (DSP) controlled PWM switching-mode power supply (SMPS). This SMPS is employed phase-shifted parallel (PSP) operation of IGBTs. This technique allows ± 350 A, 2.5 Hz stair output, and ± 350 A at bipolar mode operation. Current feedback and input voltage feed-forward control schemes are applied to improve the output current stability. Experimental results showed that the implemented converter achieved a useful versatile power supply.

A Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers
In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
