Framework for standardizing development and deployment of services
A framework that provides for development and deployment of services that future-proofs application development efforts, avoids vendor “lock-in” at the PaaS level, and offers true portability of applications and services. Using the framework, developers write application code to a common API interface that connects to resources. The API interface obtains configuration data from a configuration provider that provides configuration data. The configuration data points to an implementation of the code that is bound at runtime. This results in a separation of the API from the configuration data. Using the framework, the application code is portable and can be moved from one framework to another so long each of the frameworks adhere to the common API interface. As such, application code may be written once and then implemented on one or more cloud-based infrastructures and/or within an on-premises data center. |

Service based testing
Some tests can be implemented as services. A network provider can deploy (“push”) a test to a container resident on one or more devices of the network, either at installation, periodically, or when a problem is reported. When a customer reports an issue, services running on one or more devices of the customer's installation can cause the containerized tests to be run. For example, the central office of the network provider can initiate a request to run the test through the internet (or other connection) by the container. In some implementations, there is an overlap of the service based test set with traditional technician initiated test sets forming a hybrid testing architecture. |

Very high efficiency soft switching converter AKA the adjud converter
In this invention we introduce the concept of a soft switching half bridge switching cell wherein the soft switching is guaranteed by the magnetizing current. Further this soft switching half bridge cell contains at least two synchronous rectifiers in the secondary which are conducting together during the dead time of the primary switchers creating a short circuit across the secondary windings, trapping the magnetizing current and release the magnetizing current to discharge the parasitic capacitances across the primary switchers when the synchronous rectifiers turn off. The secondary windings are connected to a synchronized and controlled current source. The current demanded by the current source is shaped in such way that the current becomes zero before the synchronized rectifiers turn off, allowing the magnetizing current to discharge the parasitic capacitances of the primary switching elements in a monotonic way and create zero voltage switching conditions for the primary switchers and further charge in a monotonic way the parasitic capacitances of the secondary synchronous rectifiers without ringing and spikes. By shaping the current of the synchronized current source to reach zero before the secondary synchronous rectifiers turn off, soft switching is maintained in the half bridge cell under all line and load conditions.In one of the key embodiments the current of the synchronized current source will reach zero before the primary switchers turn off. In such configuration the dead time between the conduction of the primary switchers can be reduced to the transition time.This invention is proposing different ways to shape the current of the current source, some of the configuration being forward derived and some of them boost derived. These technologies are suitable also for bidirectional power transfer and for multiple independent outputsThe family of converters derived from the soft switching half bridge cell can be applied in many power conversion applications especially at high frequency due to guaranteed soft switching in all the line and load conditions.The methodologies of shaping the current of the syncroniosed current source do apply also to other topologies such as single ended forward converters. |
