摘要： A DC Link for use with a multi-phase DC to AC converter provides soft-switch opportunities to the main inverter devices only when such opportunities are required. A quasi-resonant rail swings from source to ground potential either with or without the assistance of an auxiliary switch. The quasi-resonant rail swings from ground to source potential with the assistance of an auxiliary switch. Low switch stresses are characteristic in both the main inverter switch devices and the DC link switch devices. Main power is carried predominantly through a DC link switch thereby minimizing power handling requirements of DC link reactive components.

摘要： Control methods for operating a power converter circuit, consisting of a full bridge DC/DC converter stage and a full bridge DC/AC inverter stage, for use in automobiles and other vehicles. The DC/DC converter is operated by pulse width modulation and by “soft switching” and “synchronous switching” which involves turning MOSFET switches OFF and ON at strategic times to gain improvements in system performance. The DC/DC converter is also operated at a relatively high and relatively constant duty cycle, and is controlled in such a way as to make the output operate as a current source. The DC/AC inverter has a cycle by cycle overload current protection scheme.

摘要： An inverter circuit operating from line utilizes minimum, lower rating switches to operate at higher frequency, while maintaining substantially unity power factor and lower input current harmonics. The input rectified DC is transferred to a storage capacitor using a buck-boost regulator in which the current in inductor is always maintained discontinuous and proportional to the instantaneous input voltage. Filtering this input current will give substantially sinusoidal current at the input. The second switch in the buck-boost regulator and an additional third switch contributes to the necessary half bridge for an inverter. The inverter, which can be self oscillating or driven from a control circuitry, can give higher frequency, high voltage AC output with ability to control the load power hence provide for dimming, e.g. for a fluorescent lamp.

摘要： A method and system for detecting faults in an electric power-assisted steering system includes determining a voltage vector of an electric power-assisted steering motor and measuring a current vector of the motor. Acceptable angular relationships are defined between the voltage vector and the current vector, which are then compared to find a fault if the angle does not meet the acceptable angular relationship. Additionally, motor direction and position can also be used against an angular check of the voltage and/or current vector. Similarly, torque direction can be used. In this way, several different faults can be determined dynamically under transient conditions.
