摘要： A transmitter identification information (TII) signal detection circuit is suitable for an orthogonal frequency division modulation system. A TII signal detection circuit receives a TII signal and conducts a cross-correlation calculation on the TII signal and a phase reference symbol (PRS) so as to obtain a present cross-correlation result, and then, sums the cross-correlation results obtained by conducting cross-correlations on AVE_TF_NUM-1 pieces of TII signals and the PRS and the present cross-correlation result so as to obtain an accumulated cross-correlation result. After that, a plurality of indices corresponding to a plurality of maximal values in the accumulated cross-correlation result is found out according to the accumulated cross-correlation result. Finally, a present main identifier (MainId) and a present sub-identifier (SubId) are calculated according to the four indices corresponding to the four maximal values, wherein the cross-correlation calculation is conducted on the TII signal and the PRS of every two adjacent sub-carriers.

摘要： A switching power converter detects low load conditions based on the ratio of a first peak current value for peak current switching in constant voltage regulation mode to a second peak current value for peak current switching in constant current regulation mode. The power supply load is considered to have a low load if the ratio is lower than a predetermined threshold. Once a low load condition is detected, the switching frequency of the switching power converter is reduced to a level that minimizes switching loss in the power converter. In addition, the switching power converter also adjusts the switching frequency according to the sensed input line voltage. An offset is added to the switching period to reduce the switching frequency of the switching power converter, as the input line voltage is increased.

摘要： In a switching power converter, PWM mode and PFM mode are separated into two independent control sections with the control voltage range in each control section determined independently. Each of the PWM and PFM modulation modes cannot operate continuously beyond its boundaries, thereby forming a control gap between the two control sections within which no continuous operation is allowed. In order to supply a load condition within the control gap, the power supply operates at the two boundaries of the control gap. Transition between PWM and PFM modes occurs fast, with low output voltage ripple. No limitation needs to be imposed on the control voltage range in each of the PWM and PFM control sections, because the control parameters in the PWM and PFM control sections need not be matched to one another, due to separation of the PWM and PFM modes by the control gap.
摘要翻译：在开关电源转换器中，PWM模式和PFM模式分为两个独立控制部分，每个控制部分的控制电压范围独立确定。每个PWM和PFM调制模式都不能连续超过其边界，从而在两个控制部分之间形成一个控制间隙，在这两个控制部分之间不允许连续的操作。为了在控制间隙内提供负载条件，电源在控制间隙的两个边界处工作。 PWM和PFM模式之间的转换发生得很快，输出电压波动较小。在PWM和PFM控制部分的每个PWM控制部分的控制电压范围不受限制，因为PWM和PFM控制部分中的控制参数不需要彼此匹配，这是由于PWM和PFM模式的分离控制差距。

摘要： A hybrid constant current control system that uses both pulse width modulation (PWM) and pulse frequency modulation (PFM) control. When transitioning from constant voltage mode to constant current mode the present invention can continue to control using PWM. Thereafter, when the voltage has dropped, the present invention smoothly transitions to PFM mode. The point of transition is based upon the switching frequency and the lowest rated voltage of operation. The system and method avoids very short (narrow) Ton times which ensures accurate constant current (CC) control with bipolar junction transistor (BJT) devices. The present invention also avoids acoustic noise because the switching frequency is maintained at a high enough level to avoid such acoustic noise even when the energy transferred through the transformer is still substantial and the output voltage is not too low. In addition the output current limit is insensitive to variation in the inductance-input voltage ratio, and is minimized against leakage inductance.
摘要翻译：一种采用脉宽调制（PWM）和脉冲频率调制（PFM）控制的混合恒流控制系统。当从恒定电压模式转换到恒定电流模式时，本发明可以使用PWM继续控制。此后，当电压下降时，本发明平滑地转变为PFM模式。转换点基于开关频率和最低额定工作电压。该系统和方法避免了非常短（窄）的Ton次，从而确保使用双极结型晶体管（BJT）器件进行精确的恒定电流（CC）控制。本发明还避免了声学噪声，因为即使当通过变压器传送的能量仍然很大并且输出电压不是太低时，开关频率被保持在足够高的水平以避免这种声学噪声。此外，输出电流限制对电感 - 输入电压比的变化不敏感，并且对漏电感最小化。
