چکیده

در این مقاله روش کنترلی چندحالته‌ی جدیدی، با هدف بهینه‌سازی بازدهی مبدل نیم‌پل در تغییرات جریان بار پیشنهاد شده‌است. بهینه‌سازی بازدهی تنها با استفاده از تغییر حالت کنترلی و بدون اضافه کردن المان به ساختار اصلی مبدل صورت می‌گیرد. روش پیشنهادی از حالت‌های کنترلی مطرح، شامل حالت کنترلی نامتقارن، شیفت ضریب وظیفه، PWM متقارن و پالس منقطع استفاده می‌کند. برای اولین‌بار نقاط گذر بین حالت‌های کنترلی که مقادیر مشخصی از جریان بار هستند، به‌صورت تحلیلی و برمبنای مقایسه تلفات مبدل نیم‌پل در حالت‌های کنترلی مختلف، محاسبه می‌شوند. نقاط گذر به‌عنوان معیاری برای تغییر حالت کنترلی استفاده شده و تابعی از پارامترهای مبدل نیم‌پل هستند. در روش پیشنهادی، جریان بار در هر لحظه با نقاط گذر مقایسه شده و مبدل در حالت کنترلی با بالاترین بازدهی ممکن قرار می‌گیرد. بدین‌ترتیب بازدهی مبدل نیم‌پل، برحسب حالتهای کنترلی و در سراسر بازه تغییرات بار، بهینه می‌شود. صحت و دقت معادلات نقاط گذر و برتری روش پیشنهادی نسبت به روش‌های پیشین، با ارائه نتایج عملکرد آن نشان داده شده‌است.

چکیده [English]

In this paper, a new multi-mode control method is proposed to optimize the efficiency of the half bridge converter under the load variations. Efficiency optimization is performed by only changing the control mode and without adding elements to the main converter structure. The control method uses the prominent control modes including asymmetrical, duty phase shift, pulse width modulation (PWM) and burst control. For the first time, three transition points between control modes, being the specific values of the load current, are analytically calculated based on full bridge converter power losses. Transition points are used as the criteria for allocating the control mode and are functions of the half-bridge converter parameters. The proposed method continuously compares the load current with the transition points and puts the converter in the control mode with the highest efficiency. Thus, the half-bridge converter efficiency is optimized in terms of control modes and over the load variations. The accuracy of the analytically determined transition points and superiority of the proposed control method to the previous ones is determined by illustrating the performance of the converter.
