WebThe effects of the transformer’s parasitic capacitance is to extend the “spike” width past the blanking time causing the LT1070 to mistrigger, as shown in Figure 5. The duty cycle variations in the switch pin (Trace A) and switch cur-rent (Trace B) waveforms are the result of this problem. WebMay 28, 2024 · 10. The design of this R C D clamp requires the knowledge of the maximum peak current your controller can set up as well as the maximum voltage you tolerate across the MOSFET. I have presented all these equations in a seminar I taught at APEC in 2011 and entitled The Dark side of the Flyback Converter.
