“…In wide range applications, R TC varies a lot; no load condition is also a valid operating point. The PS ZVS converter [8] is less suitable in light load and no-load applications. Large circulating current in Mosfets and anti-parallel diodes would result large power loss in Q2, Q3.…”

One of the most prominent application areas of induction heating principle is for sealing of caps of plastic and glass containers. It is increasingly being used to seal containers with extremely wide range industrial products. The process ambience around the controller for sealing of bottles containing different types of products could be different. Such prospects, often, could act as constraints for design of power controllers. Dust prone environment prevailing in processes such as for sealing nutraceuticals, coffee, a few pharma products, etc. recommends use of air-tight enclosure. It does not have any ventilation, even the natural air movement inside or the free convection is restricted. This article proposes that the internal convection could still be made effective by creating requisite buoyant force where both power converter topology and component engineering could play important roles. The topology should optimally reduce the power loss and surface temperature of components should be high. The proposed idea has been validated by designing a zero-ventilated 1.5 kW, 50 kHz induction heating system that includes the induction coil head.

“…Accurate and efficient control of power delivered to foil is prerequisite for quality sealing of wide range bottles. The PS ZVS converter [8] is less suitable, particularly, for light load and no-load applications. Large circulating current in Mosfets and anti-parallel diodes would result large power loss in Q2, Q3.…”

“…Both core and copper loss should be minimum 2. ZVZCS helps maximize the value of n at n max (8) where the value of P cu is minimum, current in primary and copper length at secondary are minimized, and, 3. The value of K (12) of core material should be large.…”

“…The quality requirements in the biomedical or automotive electronics industries are stringent, with higher safety requirements. Therefore, we used the multiplex testing method to reduce the errors that occur during testing, the mobile test guardband to reduce the generation of killing errors and missing errors, and obtain products with near-zero defects [22][23][24][25][26][27][28]. Multiplex testing can improve the test yield and test quality; however, if the test time and the number of tests are increased, the test cost will gradually increase.…”

“…Various work can be found in the literature taking advantage of both standalone FP-GAs [11][12][13][14][15] and Zynq SoCs [10,[16][17][18][19][20][21][22][23][24][25] to control power electronics devices. Most presented Zynq-based solutions use development boards for prototyping [10,17,[19][20][21][22]24,25], including the Zedboard used in this paper [10,[19][20][21]24]. A custom hardware platform is proposed in [17] specifically for power electronics control.…”

Many advanced power electronics control techniques present a steep computational load, demanding advanced controllers, such as FPGAs. However, FPGA development is a daunting and time-consuming task, inaccessible to most users. This paper proposes a complete methodology for prototyping power electronics with Xilinx Zynq-based boards using Matlab/Simulink and HDL Coder. Even though these tools are relatively well documented, and several works in the literature have used them, a methodology for developing power electronics systems with them has never been proposed. This paper aims to address that, by proposing a complete programming and design methodology for Zynq-based power electronics and discussing important drawbacks and hurdles in Simulink/HDL Coder development, as well as their possible solutions. In addition, techniques for the implementation of all required peripherals (ADCs, digital outputs, etc.), system protections, and real-time data acquisition on Zynq boards are presented. This methodology considerably reduces the development time and effort of power electronics solutions using Zynq-based boards. In addition, a demonstration Simulink model is provided with all proposed techniques and protections, for use with a readily available development board (Zedboard) and ADC modules. This should further reduce the learning curve and development effort of this type of solution, contributing to a broader access to high-performance control prototyping using Zynq-based platforms. An application example is presented to demonstrate the potential of the proposed workflow, using a Zedboard to control a multilevel UPS inverter prototype with Model Predictive Control.
