This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

A state feedback control method for an interleaved boost power converter is designed, which, in turn, can achieve interleaved current sharing among parallel-connected converters. The state feedback control in the continuous time domain is derived using the pole placement technique and linear quadratic optimal method. The load estimator is designed by deriving a full-order state observer to ensu...

A low-side switch is a MOSFET or an IGBT that is connected to the ground-referenced and is not floating. In a boost converter, the source terminal of the MOSFET is connected to the circuit ground, which is referred to a low-side MOSFET. To switch an N-channel MOSFET of a boost converter on, the V should be in the order of 10 to 20V. Since the source terminal is grounded, this implies that the g...

1 This work is supported by Philips Research, Briarcliff Manor, NY, through Colorado Power Electronics Center Abstract – In converters for power-factor-correction (PFC), universal-input capability (ability to operate from any AC line voltage, world-wide) comes with a heavy price in terms of component stresses and losses, size of components, and restrictions on the output DC voltage. A new two-s...

Conventional two-state dc to dc voltage converters have in their small signal transfer function a right half planzero in pole-zero plane whichthis zero result in speed reduction and lowfrequency operation, especially, because position of the zero is not fixed andmovesby the load variation. To remedy this problem the tri-state boost converters have been introduced. These converters haven’t the m...
