چکیده مقاله :
انتقال القایی توان یکی از تکنولوژیهای برتر اخیر میباشد که به کمک آن میتوان اتصالات الکتریکی را در هنگام انتقال انرژی الکتریکی حذف کرد. کاربردهای متنوعی از این تکنولوژی ارائه شده که یکی از آنها تغذیه بارهای ac در قالب G2V و موتورهای تکفاز است. برای تغذیه بارهای ac، توان خروجی مبدل القایی توان پس از یکسوشدن در اختیار یک اینورتر قرار میگیرد. تبدیل متوالی dc/ac/dc/ac در فرایند انتقال القایی توان سبب کاهش بازده IPT میشود که بخشی از این کاهش بازده ناشی از تلفات کلیدزنی در IPT میباشد. برای ساخت شکل موج ولتاژ ac دلخواه با THD قابل قبول از یک منبع ولتاژ dc، فرکانس کلیدزنی میبایست چندین برابر فرکانس موج مرجع باشد. در این مقاله بر اساس مشخصه بهره- فرکانسIPT ، روش جدید سنتز شکل موج PFSW بر پایه مدولاسیون فرکانس پالس ارائه میشود. روش PFSW تلفات کلیدزنی اینورتر سمت ثانویه را قابل صرف نظر کردن میکند. همچنین نشان داده میشود که روش PFSW علاوه بر کاهش تلفات کلیدزنی، سبب کاهش مجموع توان المان کلیدزنی (TSDP) برای مبدلهای سمت ثانویه IPT و افزایش طول عمر مبدلهای به کار رفته میشود. در این مقاله صحت ادعای بیانشده از طریق روابط ریاضی و بررسی نتایج نمونه آزمایشگاهی اثبات میشود.
The electrical connection between the load and source can be eliminated using inductive power transfer. Supplying AC Loads, such as V2G and single phase motors, is one of the many applications of IPT. To supply an AC load, the rectified output power of IPT should be delivered to an inverter. The sequential dc/ac/dc/ac conversions cause IPT efficiency decreases. To make an output AC voltage with acceptable THD, the carrier frequency of the PWM method should be several times the reference frequency which increases the switching loss. In this paper based on IPT gain-frequency characteristics, a new pulse frequency waveform synthesizing method (PFWS) has been presented. This method eliminates secondary inverter switching losses. It is shown that besides loss reduction, synthesized sinusoidal waveform at secondary of IPT, causes the Total Switching Device Power (TSDP) of secondary converters decrease, therefore their lifetime increase. Simulated and experimental results of the developed laboratory model which verify and illustrate the operation of the proposed method are presented.
