20170201170 | METHOD FOR GENERATING HIGHLY EFFICIENT HARMONICS FREE DC TO AC INVERTERS - This invention presents a highly efficient harmonics free DC-AC power inverter using a pair of push-pull switches with feedback loop that acts as a voltage regulator. The feedback loop voltage regulator uses a series-shunt feedback amplifier to regulate the output voltage by amplifying the error signal between a pure sine wave referenced signal and the measured output voltage signal. A step-up low power transformer is used to step-up the triggering pulse at gates of the push-pull solid state switches to the desired rated output voltage so that the output voltage becomes harmonic free sine wave, but high voltage feedback amplifier, if feasible, maybe used without using the transformer. The reference signal may be synchronized with the grid for on grid applications, but it can also be used for stand alone loads. In order to optimally minimized the conduction power loss across the push-pull solid state switches of the DC-AC inverter, the positive voltage V+ and the negative voltage V− must be regulated and controlled, so that the voltage across the push-pull switches are minimized. Hence, two DC-DC converters are used to generate the regulated voltages V+ and V−. Each of those voltages is controlled using a feedback loop that drives the pwm of the DC-DC converter. At this point, the conduction power loss of the DC-AC push-pull solid state switches are optimally minimized, but the DC-DC converters are not. In order to minimize the conduction power loss of the DC-DC converters, two multilevel converters with n-array series voltage sources, or n-array series capacitors, are used. The voltage level at the top of each capacitor is carefully selected so that the overall conduction power loss of the DC-DC converters is minimized. The power conduction power loss proportional to the number of levels used but this comes at higher cost and complexity. | 2017-07-13 |
20170201171 | Pre-Bias Startup of a Converter - A method includes comparing, by a voltage-second (VS) controller, a first duty cycle used to control a first switch at a primary side of a power transformer of a DC-to-DC converter with a threshold. The method further includes if a value of the first duty cycle is less than the threshold, controlling, by the VS controller, a second duty cycle used to control a second switch at a secondary side of the power transformer, and maintaining a voltage level at an output voltage node at a non-zero value, and if the value of the first duty cycle is greater than the threshold, controlling, by an output voltage loop, the second duty cycle based on the first duty cycle, and monotonically increasing the voltage level the at the output voltage node from the non-zero value to a predetermined value. | 2017-07-13 |
20170201172 | Electronic Control Device - In a step-up circuit, which is an electronic control device, changes in current caused by a current rise when stepping up is started and a current drop when stepping up is stopped generate magnetic induction noise due to fluctuations in the electromagnetic induction voltage in signal lines around the step-up circuit. The present invention is a step-up circuit for stepping up by current control, wherein the step-up circuit is provided with a plurality of target current values for retaining a step-up current so that the current is raised in a stepwise manner when stepping up is started and dropped in a stepwise manner when stepping up is stopped. The present invention reduces electromagnetic induction noise generated by the changes in current when stepping up is started and when stepping up is stopped. | 2017-07-13 |
