摘要： In the present legacy electrical power generation and distribution system, the power quality delivered to end consumers is being degraded by a number of disruptive technologies and legislative impacts; especially with the rapidly increasing myriad of privately owned and operated domestic and commercial distributed energy generation (DEG) devices connected at any point across a low voltage (LV) distribution network. The present invention bypasses this increasing critical DEG problem by offering a solution comprising an energy processing unit (EPU) that is installed at the customer's electrical power point of use (POU). And because of the controlled tightly voltage regulated output of the EPU, significant energy savings can be achieved through dynamic voltage control, utilizing the CVR effect, reduced reactive power demand, and reduced or eliminated peak demand billings.

摘要： In electronic systems, the downstream circuitry may be damaged by overcurrent and overvoltage events. Therefore, there is provided a dual protection device for protecting electrical components in electronic systems. The protection device includes a mechanical fuse in conjunction with an electronic fuse, eFuse, the two components connected in series, together protecting against overcurrent events on two levels. The mechanical fuse provides high overcurrent protection, realising fast and reliable protection at high overcurrent events, and the electronic fuse provides low overcurrent protection, realising accurate and resettable protection for low overcurrent events.

摘要： The present invention comprises the combination of one or more micromachined circuit elements and a micromachined DC-to-DC step-up converter on the same or different substrates, so as to allow the operation of the micromachined circuit element at a different voltage, typically a higher or a negative voltage, in comparison to the input power supply to the system. The micromachined structure of such a converter requires little chip area and is normally fully compatible with the micromachined structure of other micromachined circuit elements, such switches and resonators, providing obvious advantages when formed on the same substrate as such devices. Similarly, micromachined switches have the advantage of providing substantially greater isolation between the signal being switched and the signal doing the switching, and provide a much better ratio between the off resistance to the on resistance than can be achieved with transistor switching devices, such as by way of example, MOS switches. Micromachined resonators also offer many advantages, such as an equivalent of tuned circuits with very high Q factor, and do so without requiring inductors or active devices in oscillatory circuits having a risk of instability, and of allowing the realization of the equivalent of complicated tuned circuits in a small chip area.

摘要： In accordance with disclosed embodiments, a power conversion system and method are provided. The power conversion system comprises a main power source configured to deliver drive power to a load and an add-on power module. The add-on power module comprises an isolated DC/DC converter and a low voltage source coupled in series with a high voltage source. The add-on power module is coupled to the main power source and the load and configured to output boost power to the load. The power conversion system further comprises a controller coupled to the main power source and the add-on power module, wherein the controller is configured to: determine that the load requires power from the main power source, and if so, direct boost power from the add-on power module to the load; and direct drive power from the main power source to the load when boost power falls below a predetermined threshold.
