    • A boost converter topology is disclosed that includes a resonant network comprising a snubber inductive element having a primary winding connected in series to a first resonant diode that is connected, at a first node, to two series connected additional resonant diodes and a secondary winding coupled to a fourth resonant diode connected to the first node. The present invention has the advantage of reducing the energy stored in the parasitic capacitor of the first resonant diode by a factor of four at the turn off of the main control switch. This reduction is achieved by allowing only a small amount of energy transfer to the snubber inductive element so that it does not turn the two additional resonant diodes on before the auxiliary switch is turned on, thus reducing losses and EMI associated with turning on the auxiliary switch.
    • 公开了一种升压转换器拓扑,其包括谐振网络,其包括缓冲电感元件,该缓冲电感元件具有与第一谐振二极管串联连接的初级绕组,该第一谐振二极管在第一节点处连接到两个串联的附加谐振二极管和耦合到 连接到第一节点的第四谐振二极管。 本发明的优点在于,在主控开关断开时,将第一谐振二极管的寄生电容器的能量减少了四倍。 这种减少是通过仅将少量的能量传递到缓冲电感元件来实现的,使得在辅助开关导通之前它不会使两个附加的谐振二极管导通,从而减少与辅助开关导通相关的损耗和EMI 。

    • A current management system for a telecommunications power system includes a power bus, a communications bus, and a distribution module connected to the power bus and the communications bus. A plurality of loads are connected to the distribution module. A plurality of rectifier modules are connected to the power bus, the communications bus and to at least one alternating current source. Each of the rectifier modules includes a neuron that generates a rectifier current signal for the rectifier module. A master controller that is connected to the communications generates an average current signal from the rectifier current signals. The neurons generate a first rectifier control signal that slightly modifies current that is output by the rectifier modules based upon the average current signal and the rectifier current signal. A temperature sensor senses a temperature of each of the rectifier modules. The master controller generates an average temperature signal from the rectifier temperature signals. The neurons generate a second rectifier control signal that slightly modifies the current that is output by the rectifier modules using the average temperature signal and the rectifier temperature signal. In another current management system, the neurons communicate to establish a highest rectifier current. The neurons of each rectifier module adjust their rectifier voltages based on the highest rectifier current to approximate current balancing.

    • A soft switched PWM AC to DC power converter for a DC power supply is disclosed. The power supply includes a power factor corrector (PFC) converter with a power boost topology, a DC/DC converter with a forward topology and a fly-back converter which serves as an auxiliary power supply for the controller components. The three converters are synchronized by a gate array logic (GAL) IC to minimize EMI noise. The GAL also conditions the PWM for the PFC and the DC/DC converter to provide very precise switching control. Synchronizing and PWM timing signals are derived by the GAL using a high-speed clock signal that is input to the GAL as a data input. The clock signal is repeatedly divided using synchronous division to yield a digital monostable timing signal that enables very precise control of converter switches.
