In this work a new embedded negative voltage level converter is presented. The proposed circuit converts a positive input signal to a negative output signal obtaining an increased protection by the high voltage stress on the used MOS devices. This results in higher system reliability in applications where negative pulses are required. The circuit has been designed in a 0.18μm triple-well standa...

Employment DC-DC switching power converters in many different areas become is very important. In this paper, three models of the photovoltaic solar module were proposed order to designing, implementation, and simulated them MATLAB/Simulink with boost converter circuit first then positive output super lift Luo (POSLL) again. A comparison was made between two circuits, as well a theoretical simul...

Under unbalanced supply condition low order harmonics will appear at the input and output terminals of the PWM AC to DC converter. Based on the positive and negative sequence components, an unbalanced transfer matrix in terms of the input phase voltages is derived. An on-line method using a neural network (NN) is used to implement this transfer matrix. It is shown that by using an additional lo...

As generally acknowledged, the high-gain DC-DC converter is widely used in the sustainable energy system as the front-stage of the DC-AC converter. Therefore, it is indispensable for low voltage to be boosted to high voltage. In general, the boost converter or the buck-boost converter is widely used in such applications. However, it is not easy for such converters to achieve high voltage ratio....

Random torque disturbances generated by magnetic bearings eccentric magnetic force have negative effects on the output torque precision of the magnetic suspended reaction flywheel(MSRFW). In order to eliminate the negative effects, dynamic models of flywheel system including motor and the buck DC-DC converter are established and a synergetic control approach for speed mode operation is presente...

Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...
