摘要： This invention presents a method that generates a harmonics free AC voltage at a specific frequency, such as 60 Hz, from unregulated DC source by precisely biasing complementary push-pull NOMS and PMOS switches. The precise bias triggering pulse is continuous pulse that is created using a feedback linear regulator. Since the feedback linear regulator uses low power electronics such as op-amps and comparators, the bias triggering pulse is stepped up using low power step-up transformer for high voltage applications. The step-up transformer is used to step-up the bias triggering pulse at the output of the feedback amplifier to drive the solid state switches precisely so that the output is harmonic free sine wave. In order to minimize the power losses by the switches, two DC-DC converters are used to control the voltages across the NMOS and PMOS switches. One DC-DC converter generates a positive voltage that is connected to the drain of the NMOS switch; where its voltage follows the output voltage during the positive half cycle of the load's current. The other DC-DC converter generates a negative voltage that is connected to the drain of the PMOS switch and it follows the output voltage during the negative half cycle of the current. Hence, a power factor controller is not needed as the NMOS automatically conducts when the load current is positive and the PMOS automatically conducts when the load current is negative. This method is applicable to a single phase as well as three phase system, and for a standalone load as well as for grid connected load. Also, this method does not require the need for a high power filter or bulky inductors to remove the harmonics as the harmonics are removed by precisely biasing each switch during its conduction.

摘要： A power factor correction conversion device and control method thereof are adapted to send an AC signal to a power factor correction conversion device, convert the AC signal into a DC signal, and perform power factor correction of the DC signal, so as to change a power factor sent to a back-end load, wherein the control method includes a rectification step, a feedback step, a ripple calculating step, a ripple offsetting step, a logical computation step, a pulse width modulation step and a power factor correcting step. Hence, the second-order ripple component in a feedback signal is eliminated to thereby increase the response speed of the power factor correction conversion device and reduce the distortion rate of the current, thus increasing the power factor sent to the back-end load.
