    摘要： A dual voltage power conversion system with power factor correction (PFC) having a capabilities to adjust a PFC setpoint according to operating conditions. The input signaling levels, for example, may be monitored and used to control adjustments to the PFC setpoint in order to allow the PFC setpoint to dynamically change with any input variation. The PFC setpoint may be adjusted to a PFC setpoint resulting in maximum efficiency.

    摘要： A cooling system is operable to facilitate cooling a power module or other electronic assembly. The cooling system may be configured to facilitate cooling a DC/AC inverter or other electronic assembly where two power modules may be arranged in an opposing relationship relative to a coolant passageway. The opposing relationship may be suitable to minimizing a packaging size and footprint required to facilitate interacting both power modules with the coolant flow.

    摘要： A power converter may employ a planar transformer to minimize winding conduction loss, and the switching devices of the power converter may be aligned in lines parallel to an edge of the planar transformer to minimize the termination leakage inductance. The windings of the planar transformer may be thermally conductively coupled to one or more heat sinks carried by a circuit board which are with respective ones of the switching devices, to provide a cooling path for the planar transformer.

The power conversion device is configured to control a first switch for enabling a first known resistance to receive the high voltage and to measure a first voltage between a first node and a ground in response to the first known resistance receiving the high voltage. The power conversion device is further configured to measure a second voltage between a second node and the ground in response to the first known resistance receiving the high voltage and to determine a first leakage resistance between the first node and the ground based on at least the first voltage and the second voltage. The first leakage resistance indicating whether the high voltage is isolated from the ground.
