摘要： An electronic package which has a heat sink that is attached to the lead frame of the package with a material that is both electrically and thermally conductive. The lead frame is also coupled to a first surface of an integrated circuit die with tape automated bonded (TAB) leads. The low thermal resistance of the heat sink increases the thermal performance of the package. The heat sink may also be mounted directly to the die with a conductive material so that the die is electrically grounded to the heat sink. The heat sink is then bonded to the leads of the lead frame that are dedicated to ground. In this embodiment, the heat sink provides the dual functions of a ground plate and a heat spreader.

摘要： Systems, methods, and devices relating to a DC/AC inverter. The inverter has a full bridge converter and an output filter with an integrated magnetic subcircuit. The subcircuit has main and auxiliary inductors and is designed to steer the current ripple of the inverter's output to the power semiconductors in the full bridge converter. By doing so, zero voltage switching is achieved by the power semiconductors, thereby mitigating switching losses. At the same time the current ripple in the inverter's output is attenuated.

摘要： Systems, methods, and devices relating to power converters. A power conditioning system uses multiple DC/DC power converter blocks. The output of each of the converter blocks is received by an energy storage and combiner block. The output of the combiner block is then received by a DC/AC inverter. The various components of the power conditioning system are controlled by a central controller. The power semiconductors within each DC/DC converter are controlled by a subsystem of the central controller and MPPT is also provided by the central controller. Also provided for are a novel three-phase DC/AC inverter topology with reduced output ripple and a control scheme for controlling the power semiconductors in the DC/AC inverter.

摘要： Systems related to controlling a DC/AC converter. A control system uses a nonlinear adaptive observer to estimate the state variables inverter current and converter voltage using a sensed grid current and a bus voltage as inputs. For non-observable points (such as when the duty cycle=0.5), the required information can be found from the DC bus voltage.

摘要： This invention provides an integrated power supply for a controller of an electronic ballast for a fluorescent lamp. The integrated power supply couples output power from the electronic ballast and uses the coupled power to provide power to the controller. In one embodiment, the electronic ballast may include a rectifier for converting an alternating current input voltage into a direct current output voltage, and a circuit including a combined power factor correction (PFC) stage and an inverter, wherein the PFC stage and the inverter share a switch. Also provided is a controller for an electronic ballast. The controller may include a voltage mode or current mode duty ratio controller that controls a duty ratio of a switch of the ballast. The controller and the ballast allow dimming of the fluorescent lamp while maintaining a high power factor.

摘要： Circuits and methods relating to the provision of a reactive current to ensure zero voltage switching in a boost power factor correction converter. A simple passive circuit using a series connected inductor and capacitor are coupled between two phases of an interleaved boost PFC converter. The passive circuit takes advantage of the 180° phase-shift between the two phases to provide reactive current for zero voltage switching. A control system for adjusting and controlling the reactive current to ensure ZVS for different loads and line voltages is also provided.
