WebOct 13, 2005 · An LM5020-controlled PWM flyback dc/dc converter, IC 1, evaluates the dither circuit’s effectiveness. The circuit’s fundamental operating frequency is 250 kHz, which the controller’s R T resistor sets. The red trace of Figure 2 shows the conducted emissions on the circuit’s positive input-power line without the dither circuit in ... WebValve sensitivity and dither movement are influenced by coil properties, switching frequency, and duty cycle. Valve reaction to a PWM signal is most sensitive when operated in a specific switching frequency range (f) at an optimal duty cycle.
