摘要：一种具有双BOOST升压线路的背光驱动电路，包括：电源模块（5）、第一电感（L1）、第二电感（L2）、第一整流二极管（D1）、第二整流二极管（D2）、LED灯串（4）、恒流驱动芯片（6）、电容（C）、第一MOS管（Q1）、第二MOS管（Q2）、第一电压比较器（7）及恒压源（8）。该背光驱动电路利用一电压比较器（7）来产生两相位相反的驱动信号分别驱动双BOOST升压线路中的两MOS管（Q1，Q2），从而使得两BOOST升压线路交叉工作，汇合到电路后端的电流为近似的直流电流，其幅值等于单BOOST升压线路中的三角波峰——峰值，提高了电路的输出功率，且不会出现幅值加倍的情况，这样就不需要增加整流二极管的规格，降低了生产成本，可以减少输出电流的紋波大小；避免了双BOOST升压线路同时工作加倍电磁干扰的现象。

摘要： A method and apparatus for boosting the gate voltages of a CMOS switch used in an integrated circuit designed in a sub-micron CMOS process is disclosed. The CMOS switch is coupled to Vin and Vout nodes, and contains PMOS and NMOS gates. Two boosting circuits are used to change the voltage on the PMOS and NMOS gates, respectively. The voltage at the NMOS gate is boosted from V DD to (V DD + K x V DD ). The voltage at the PMOS gate is decreased from V GND to (V GND - k x V GND ). The factor k is chosen such that Vout can be sampled through the entire range of Vin = V GND to V DD , even where V DD approaches the sum of the absolute values of the threshold voltages of the respective PMOS and NMOS transistors.

摘要： A synchronous average harmonic current controller for a bidirectional resonant power converter provides efficient load invariant voltage gain. The controller includes a switched capacitor filter which averages and compensates a current signal over each half of the synchronous switching period. The control signal encodes an independent modulated phase and non-modulated differential duty cycle error response. The error response signals provide negative feedback to a pulse width modulation stage which results in reduction of the synchronous average harmonic current. At this operating point, the harmonic voltage gain is related closely to the commanded bridge duty cycles.
