Summary: In this paper, a novel variable frequency controller is proposed for a passive high power factor electronic ballast with dimming capability and low crest factor. The ballast circuit is the combination of a valley fill circuit and a new frequency modulated current fed resonant inverter. The advantage of using a current fed resonant inverter in the proposed power circuit is that it provides isolation to the driver circuit without the use of any isolation devices. The proposed controller circuit uses a simple modified 555 timer to continuously regulate the lamp current by changing the switching frequency. As a result, a low crest factor in the lamp current is achieved with a high input power factor. A detailed description of the controller circuit is given in this paper. Feedback loop analysis is also provided to study the stability issues of the proposed ballast circuit. Powersim (PSIM) simulation results are presented to highlight the merits of the proposed circuit for a T8-32 W fluorescent lamp.

High performance position controller for PMSM drives based on TMS320F2812 DSP
Abstract
This work presents a high performance position controller for drives of permanent magnet synchronous motor (PMSM) using a TMS320F2812 DSP chip. Due to the new generation DSP (digital signal processor) having the characteristics of the fast computation (150 MIPS) and the complete peripheral circuits for motor drive, a fully digital controller of PMSM drives system, which includes a current vector control scheme, SVPWM generation, A/D conversion, coordinate transformation, QEP detection and an intelligent strategy, can be integrated and realized by software within a DSP chip. For increasing the performances of PMSM drives, an adaptive fuzzy controller constructed by fuzzy basis function and a parameter adjustable mechanism is proposed and applied in the position control loop to cope with the system uncertainty and to increase a fast tracking response. To confirm the effectiveness of the proposed system, an experimental system included by a PMSM, DSP control board, inverters, and rectifier has been set up and some experimental results have validated the theoretical ones.

Abstract
digital servo system based on MC56F8357 is presented in this paper. The system principle, hardware and software architectures of the AC servo drives are introduced. By utilizing Field Oriented Control (FOC), Space Vector PWM (SVPWM), DC bus ripple compensation, digital PI regulating with correction of the integral term and Anti-Hunt Processing control strategies, the hardware and software of the servo system are implemented. Experiments including different position and speed control have been carried out and the experimental results are also given.
