[]
[null,"Quasi-Resonant (QR) flyback converter design is an iterative process.  This design tool reduces the hardware iterations by simulating the steady state operating maps that show the converter modes under different input and load conditions.  Design adjustments can be explored in order to optimize the power system.  Although the design spreadsheet is organized around a bridge rectifier – bulk capacitor line rectifier, it can be used for fixed output Power Factor Corrector (PFC) or voltage follower PFC systems.  Systems with PFC must allow the QR flyback stage to start-up under the low ac line condition.  However, the steady state conduction losses to the QR flyback stage will only occur at the PFC bulk capacitor voltage levels."]
[]
[null,"To use this tool, enter the voltages, power levels and converter estimates into the appropriate spaces of the QR Design Tool worksheet.  This step also requires an initial selection of the power MOSFET and the output rectifier.  Enter data in the cells with the BLUE text; the calculated values are in the cells with the RED text.  The parameters for the UCC28600 are already included.  The design tool will generate a recommended design that includes transformer parameters.  Verify that the current and voltage stresses are compatible with the MOSFET and output rectifier that were initially selected.  The recommended values in the design may not be practical due to integer transformer turns, standard values, etc.  Yet the operation of the converter can be significantly altered by using the closest parameter."]
[]
[null,"At this point, design the transformer using the magnetizing inductance and approximate turns ratio that was recommended by the QR Design Tool worksheet.  The Magnetic Specification sheet can be printed and used as a guideline for the recommended transformer design.  The next step is to see how the design performs using the QR Simulator worksheet."]
[]
[null,"The QR Simulator will carry over the Converter Requirements, MOSFET Specifications, Diode Data and the UCC28600 Characteristics.  The transformer information and the programming components, RS (current sense resistance), RPL (power limit programming), ROVP1 and ROVP2 (over-voltage programming resistors) must be entered by the user.  The recommended values are shown beside the cells as a reminder for the ideal values."]
[]
[null,"After entering the final values, examine the operating maps.  They reveal the boundaries of the different modes of operation.  The operating maps portray the power levels, peak switch currents, feed back voltages and switching frequencies for the full array of line voltages and loads that the converter would experience.  These maps can be used to explore design alternatives, such as different current sense resistor values, different transformers, etc.  For example, it might be desirable to change the power level where burst mode occurs in order to avoid audio noise at a common load operating point.  The QR Simulator worksheet also shows rms currents, whether the converter is in power limit, the operational mode among other potentially useful data that can be used to optimize the converter performance in a specific power system."]
[]
[null,"For PFC systems that have a fixed bulk voltage, estimate the PFC output voltage at the peak of its ripple.  Calculate the equivalent ac voltage to achieve that maximum voltage level.  Enter that ac voltage as the VAC(max) level.  Enter the minimum operational ac line voltage as the VAC(min) level because the QR Flyback must power up correctly in order to start the PFC stage."]
[]
[null,"For voltage follower PFC systems, estimate the PFC output voltage at the peak of its ripple during maximum line conditions. Calculate the equivalent ac voltage to achieve that maximum voltage level. Enter that ac voltage as the VAC(max) level. Enter the minimum ac line voltage as the VAC(min) level because the QR Flyback must power up correctly in order to start the PFC stage. In the least, converter must be designed to operate at safe temperatures under the steady state operating rms currents that occur at the minimum PFC voltage and at the maximum PFC voltage. The data tables in the QR Simulator worksheet can assist in finding the required values."]
