摘要： A voltage converter uses a component such as a JFET or four-terminal power MOSFET having no body diode and exhibiting no body diode conduction characteristic as a synchronous rectifier to reduce switching losses and body diode conduction losses and to support high frequency switching so that use of smaller components and higher current densities can be achieved. These effects are enhanced by a self-driven circuit utilizing positive feedback to enhance switching speed and reduce switching losses which increase with switching frequency.

摘要： A buck converter has a driver circuit with a drive transformer that provides complementary voltages to the buck converter switches. The drive transformer may have two secondary windings, with one winding for each converter switch. As one converter switch experiences a rising gate voltage, the other converter switch experiences a falling gate voltage. Since both converter switches are controlled by the same driver switches, the converter switch dead time is very small. Preferably, at least one converter switch has a voltage shift circuit connected to the gate electrode. Adjustment of the voltage shift magnitude will advance or delay the turn on and turn off times of the switch. Hence, the converter switch dead time can be precisely adjusted by varying the voltage shift magnitude. Preferably, the converter switch dead time is less than 1 or 2 nanoseconds.
摘要翻译：降压转换器具有驱动电路，其中驱动变压器为降压转换器开关提供互补电压。驱动变压器可以具有两个次级绕组，每个转换器开关具有一个绕组。当一个转换器开关经历上升栅极电压时，另一个转换器开关经历栅极电压下降。由于两个转换器开关由相同的驱动器开关控制，所以转换器开关死区时间非常小。优选地，至少一个转换器开关具有连接到栅电极的电压移位电路。电压偏移幅度的调整将推进或延迟开关的导通和关闭时间。因此，可以通过改变电压偏移量来精确地调整转换器开关死区时间。优选地，转换器开关死区时间小于1或2纳秒。

摘要： Common mode (CM) noise is substantially canceled in a switching power supply circuit such as a boost converter by providing a split inductor and analyzing the switching power supply circuit as a bridge circuit formed of the switch, portions of the split inductor and parasitic capacitances of respective portions of the power supply circuit. The bridge can then be balanced by addition of capacitance in parallel with the parasitic capacitance of a respective portion of the power supply circuit or dividing the split inductor such that a ratio of inductances of respective portions of the split inductor approximates a ratio of parasitic capacitances of the respective power supply circuit portions which may be measured or otherwise empirically determined. CM noise reduction of up to 40 db can be achieved without symmetric circuit design, addition of circuit elements or complex filtering having added cost, space requirements and power losses. Further, such a reduction in common mode noise allows simple EMI filtering arrangements to be employed further reducing cost and space requirements for the power supply circuit.

摘要： A voltage converter provides a desired voltage droop with load while avoiding output current sensing and active control/feedback circuits and avoiding excessive power dissipation from passive components by placing a sensing resistor in the low current, switched input circuit of the voltage converter. Therefore, the resistor conducts only when a switch controlling voltage conversion is conductive, generally at very low duty cycle and low current.
