WebIt is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination. The schematic of a flyback converter can be seen in Fig. 1. It is equivalent to that of a buck-boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: • When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. The primary current and magn…
WebMay 27, 2024 · The flywheel diode is coming out of conductance at about 1.1mS after the PWM MOSFET turns off, and you can see a period of oscillation before the next PWM pulse. Could this be the source of interference with the RF remote controller attached to the project. Something is crippling the range of the RF signal to the point where it is unusable.
