Secondary Leakage Inductance and the Rectifier Diode The transformer secondary leakage inductance may couple with the reverse recovery current IREC of the output rectifier diode to cause ringing when the diode turns off.
High-voltage resonant controller
www.st.comThe IC enables the designer to set the operating frequency range of the converter by means of an externally programmable oscillator. At start-up, to prevent uncontrolled inrush current, the switching frequency starts from a programmable maximum value and progressively decays until it reaches the steady-state value determined by the control loop.
Zero Voltage Switching Resonant Power Conversion
www.ti.comvalue L, and the magnetizing current ML., as well as the inductor’s DC resistance is negligi-ble. In addition, both the input voltage VjN and output voltage V. are purely DC, and do not vary during a given conversion cycle. Last, the converter is operating in a closed loop configu-ration which regulates the output voltage V. .

www.nxp.compop noise-free start-up. The bias-current setting of the (VI converter) input stages is related to the voltage on the MODE pin. In Mute mode, the bias-current setting of the VI converters is zero (VI converters are disabled). In Operating mode, the bias current is …
Building a DC-DC Step-Down (Buck) Converter Circuit Using ...
www.egr.msu.eduThe primary objective is to build a simple circuit of DC-DC stepping-down (Buck) converter. With the LM7809 positive voltage regulator, it is expected to have about 11V-17V DC input stepping-down to 9V DC output. And the secondary objective is to be able to achieve output voltage that is stabilized at its level.
