摘要： A boost converter in which the conventional boost diode is replaced by a bidirectional normally conducting semiconductor switch. The circuit may be implemented so the bidirectional switch is self-driven by connecting a low voltage Schottky diode between a first gate-source terminal pair. An inrush current protection function may be provided by utilizing a second gate-source terminal pair to turn the switch on and off independent of the self-driven operation in response to predetermined excessive load current conditions. The inrush current protection function is implemented by use of a second Schottky diode connected between the second gate and source terminals, and an RC circuit connecting the second gate terminal to the return rail for the converter power output transistor with an externally controlled switch connected to the RC circuit to control the bias according to the load current.

摘要： The bridgeless boost topology reduces the power dissipation, cost, and size of prior PFC systems by eliminating the intrinsic loss of the input rectifier bridge. Sensing of the input line voltage by the controller is unnecessary. The use of One Cycle Control (also known as Single Cycle Control) allows the Power Factor Correction function to be performed without complex rectification networks to obtain the AC line voltage reference. The use of bi-directional switches makes it possible to control inrush current (the startup over-current due to the charging of the output bulk capacitor), which allows elimination of over-current limiting devices and reduction of the diode surge capability requirements. Moving the boost inductor to the system input adds an additional filtering function, reducing the cost of input EMI filtering.
摘要翻译：无桥升压拓扑通过消除输入整流桥的固有损耗，降低了现有PFC系统的功耗，成本和尺寸。由控制器检测输入线电压是不必要的。使用单周期控制（也称为单周期控制）允许在没有复杂整流网络的情况下执行功率因数校正功能，以获得交流线路电压参考。双向开关的使用使得可以控制浪涌电流（由于输出大容量电容器的充电而引起的启动过电流），这允许消除过流限制装置并降低二极管浪涌能力要求。将升压电感器移动到系统输入端增加了额外的滤波功能，降低了输入EMI滤波的成本。

摘要： A high voltage rectifier device exhibiting low forward resistance and fast switching time formed of a high voltage structure connected in a cascode configuration with a low voltage structure. The high voltage structure is a bidirectional normally on semiconductor switch have two pairs of gate and source terminals which shuts off if either of the gate terminals is reverse biased. The low voltage structure is a diode, preferably a Schottky or barrier diode. The device is advantageously formed as an integrated circuit. With one of the terminal pairs of the switch clamped to zero volts, the device behaves as a diode, or the second terminal pair can be employed to provide the functions of a three terminal controlled rectifier. Among other possible applications are integrated circuits using four of the devices as a bridge rectifier, and as an anti-parallel diode for connection with an IGBT.
