Abstract: An inverter system for a vehicle including a housing, a primary stage, a secondary stage and a fault detection circuit is provided. The primary stage is configured to receive a first voltage signal from an energy power source to generate a second voltage signal. The secondary stage is configured to generate a third voltage signal in response to the second voltage signal. At least one of the primary and the secondary stages define at least one resistance point for discharging leakage current responsive to generating the third voltage signal. The fault detection circuit is configured to electrically couple the primary stage and the secondary stage to provide the second voltage signal to the secondary stage and to measure a portion of the third voltage signal to determine whether the leakage current being discharged through the at least one resistance point is within a predetermined current range.

Abstract: A vehicle ground fault detection system for detecting a ground fault includes a fault detection circuit having a resistance element. The resistance element has one side connected to a supply voltage. An electrical switching circuit is connected to the resistance element for selectably coupling the other side of the resistance element to a secondary ground. The fault detection circuit further includes a fault detection sense line connected to a junction between the other side of the resistance element and the electrical switching circuit. A controller selectably couples the resistance element to the secondary ground. The controller is coupled to the fault detection sense line to receive a voltage signal for detecting the ground fault prior to a start-up of the AC step-up power transformation. The controller determines a ground fault based on a comparison responsive to the voltage signal and a predetermined comparative value.

Abstract: A step down voltage converter for automotive electrical power supply networks reduces voltage down at least one order, for example, 42V down to 3V or lower, for the supply of microcontrollers and semiconductors. A preferred embodiment employs a tapped-inductor and three discrete components. The use of tapped-inductor is well-known and the design gives an extra-degree of freedom by the insertion of the winding ratio of the tapped-inductor into the transfer function of the Watkins-Johnson converter. It also permits the duty cycle to be adjusted to a value at which the efficiency of the converter is improved. The converter can be slightly modified and used as a multiple output converter while employing few components, diminishing the weight, size, cost and complexity of a system.
