In this paper, an interleaved soft switching boost converter for a Photovoltaic Power Conditioning System (PV-PCS) with high efficiency is proposed. In order to raise the efficiency of the proposed converter, a 2-phase interleaved boost converter integrated with soft switching cells is used. All of the switching devices in the proposed converter achieve zero current switching (ZCS) or zero volt...

A compact High Voltage (HV) module for generating 100V DC output has been developed for biasing of PIN photodiode detector used in dosimetry applications. Two different approaches have been used in designing the HV circuit. In the first case, the circuit employs a low noise, constant frequency pulse width modulating (PWM) boost converter with an inductor operating in

Electromagnetic analysis (EMA) attacks are a type of side-channel that can be performed without opening or modifying cryptographic module. In this study, we propose detection method for the measurement information, which is at preliminary stage target device as countermeasure against EMA near integrated circuits (ICs) with modules. The presence an electromagnetic (EM) field probe detected by an...

A DC–DC switching converter chip is proposed to generate both positive and negative voltages for active-matrix LCD (AMLCD) bias. An inductive boost converter and two inverting charge pumps are integrated in a proposed chip by using a 0.5 mm 5 V, 3.5 mm 30 V CMOS process. A conventional scheme used to bias AMLCD employs a switching-boost converter with several off-chip components to generate the...

Photovoltaic and wind are renewable energy resources that widely used and grow rapidly in fulfilling electricity demand. Powers from both technologies depend on sunlight intensity and wind speed. For small scale power generation, DC voltage from both technologies is low and requires step-up converter to raise DC voltage ratio before converted into AC voltage. To optimize this system, step-up co...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...
