An improved modulated carrier control (MCC) method is proposed to offer high power factor (PF) and low total harmonic distortion (THD) at a wide input voltage range and load variation. The conventional MCC method not only requires a multiplier and divider, but also is hard to be implemented with a micro controller unit without a high frequency oscillator. To overcome the problem and maintain the advantages of the conventional MCC method, the proposed MCC method adopts a current integrator, an output voltage amplifier, a zero-current duration (ZCD) demodulator of the boost inductor, and a carrier generator. Thus, it can remove a multiplier and well, as it allows for being operable with a general micro control unit. This paper presents an operation principle of the proposed control method. To verify the proposed control method, experimental results with 400 W PFC boost converter is demonstrated.

Power Point

An ultra-low power boost converter for energy harvesting applications is introduced in this brief. The idle power dissipation is reduced to 800 nW by using a novel output voltage detector (OVD) which is insensitive to temperature variation and process deviation. Furthermore, a constant on-time (COT)-based hysteretic burst mode controller with maximum power point tracking (MPPT) technique is developed to ensure high power efficiency for a wide input voltage range. After startup, the input voltage can be set as low as 30 mV. The whole system is designed and fabricated in SMIC 0.18 μm CMOS process, the end-to-end power efficiency of this converter can reach 49% at 350 mV input voltage and 65% at 750 mV input voltage.

<span>This paper presents the simulation design of dc/dc interleaved boost converter with zero-voltage switching (ZVS). By employin the interleaved structure, the input current stresses to switching devices were reduced and this signified to a switching conduction loss reduction. All the parameters had been calculated theoretically. The proposed converter circuit was simulated by using MATLAB/Simulink and PSpice software programmes. The converter circuit model, with specifications of output power of 200 W, input voltage range from 10~60 V, and operates at 100 kHz switching frequency was simulated to validate the designed parameters. The results showed that the main switches of the model converter circuit achieved ZVS conditions during the interleaving operation. Consequently, the switching losses in the main switching devices were reduced. Thus, the proposed converter circuit model offers advantages of input current stress and switching loss reductions. Hence, based on the designed parameters and results, the converter model can be extended for hardware implementation.</span>
