摘要： A PWM controller that effectively transitions between normal mode and green power mode is disclosed. A driver provides a normal drive signal during normal operation. A pulse width detector detects the pulse width of the PWM signal and if the pulse width drops below a threshold the normal mode drive signal will be turned off and a pulse ON time measurer will begin storing the pulse ON time. When the total ON time reaches a total ON time threshold or the output voltage drops below a voltage limit, a green mode drive signal will be output to the power converter. During green mode the driver will continue sending the green mode drive signal at intervals until a heavy load condition when the green mode drive signal will be shut off and the driver will resume sending the normal mode drive signal.

摘要： A secondary subcircuit of a converter circuit is disclosed where a method and circuit for operating a transistor to prevent reverse conduction of the current in the secondary subcircuit is disclosed. The diode in the secondary subcircuits of the prior art is replaced by a transistor and the circuitry for controlling the transistor is made part of the control circuit (ASIC). The secondary converter subcircuit includes a secondary coil for generating a voltage that passes through a first transistor M1, a capacitor, and a second transistor M2, where the output terminal of the subcircuit is across said capacitor. A presently preferred embodiment of a control circuit detects the voltage level at a sync node and the output voltage level at the output terminal and controls transistors M1 and M2 accordingly in generating the desired voltage level at the output terminal.

摘要： A maximize efficiency method for resonant converter with self-adjusting switching points is disclosed. The method is operated by a resonant converter, which comprises a transformer and a field effect transistor (FET). When the transistor is turned on, energy is stored in the transformer. When the transistor is turned off, a resonant signal is generated at a drain of the transistor. At this time, a suitable trigger time has to be found to turn on the transistor, so as to reduce switching power loss. The method measures the slope of the resonant signal at the trigger time. This is used as a reference to adjust the next cycle's trigger time. If the slope is negative at the time of trigger, a delta time is added to the trigger time in the next cycle, If the slope is positive, a delta time is subtracted from the trigger time for the next cycle.

摘要： A method and circuit for detecting primary switch (12) status in isolated DC/DC converters by observing the falling speed of the voltage level at the sensing point (node Z) is disclosed. It is noted that high impedance oscillation has a relatively slow falling or rising time when compared to a valid signal. By observing the falling or rising time of a given signal during the appropriate time period, a determination can be made to differentiate a valid signal and an oscillating signal. More specifically, two reference voltages (A & B) are provided to compare against node Z voltage to generate a sense pulse. A reference pulse having a predefined duration is compared to the sense pulse. If the duration of the sense pulse is greater than the duration of the reference pulse, a latch is used to generate a low output signal. If the duration of the sense pulse is less than the duration of the reference pulse, a high output signal is generated. The latch is reset when node Z voltage rises above reference voltage B.

摘要： A power diode having substantially no reverse-recovery time and relatively high conductance. The power diode is a majority carrier semiconductor having a structure that is similar to that of a metal oxide semiconductor field effect transistor (MOSFET), in that it includes a source, a drain, a gate, and a body. In one embodiment, to increase conductance of the power diode, a linked-cell configuration that reverses the geometry of a conventional cell-type MOSFET is employed, thereby increasing the width of a conductance channel over that of a conventional MOSFET, and compensating for a relatively low level of inversion in the channel region. Negative and positive feedback circuits are used to further improve the conductance of the power diode by dynamically setting a bias voltage applied between the gate and the source to a level just below a threshold voltage. In the positive feedback circuit, the magnitude of the bias voltage is greater than the threshold voltage if the power diode is forward biased, but substantially reduced if the power diode is reverse biased, thereby minimizing its turn-on delay without risking reverse conductance. Although separate components are used for biasing the device in the disclosed embodiments, it is contemplated that these components be integrated on a common substrate with the source, drain, and gate in a commercially practiced preferred embodiment. Another embodiment employs a charge carrier region diffused into the body and at least in part underlying the gate. This region provides a variable threshold voltage along the channel and reduces the effective length of the channel to increase its conductance. A threshold voltage ranges between a higher value, V.sub.TMAX, adjacent the source, to a lower value, V.sub.T, elsewhere in the device.
摘要翻译：功率二极管基本上没有反向恢复时间和相对高的电导率。功率二极管是具有类似于金属氧化物半导体场效应晶体管（MOSFET）的结构的多数载流子半导体，其包括源极，漏极，栅极和主体。在一个实施例中，为了增加功率二极管的电导，采用反转常规电池型MOSFET的几何形状的连接电池配置，从而增加电导通道的宽度超过常规MOSFET的宽度，并补偿通道区域反相水平相对较低。负和正反馈电路用于通过将施加在栅极和源极之间的偏置电压动态地设置到刚好低于阈值电压的电平来进一步提高功率二极管的电导。在正反馈电路中，如果功率二极管正向偏置，则偏置电压的大小大于阈值电压，但如果功率二极管被反向偏置，则极大地减小，从而使其导通延迟最小化，而不会产生反向导通风险。虽然在所公开的实施例中使用单独的部件来偏置器件，但是可以设想，在商业上实践的优选实施例中，这些部件在源极，漏极和栅极上集成在公共衬底上。另一个实施例采用扩散到体内并至少部分地位于栅极下方的电荷载体区域。该区域沿着通道提供可变的阈值电压并且减小通道的有效长度以增加其电导。阈值电压范围在与源相邻的较高值VTMAX之间，设备的其他位置的VT值较低。
