This paper is intended to design a parallel 50v/2A converter. The paper begins with the respective detailed working principles of PWM current control mode and voltage control mode, as well as their differences. By introducing the PWM IC UC3846 for current mode control, in order to meet the demand of duplex output, a full-bridge circuit is designed based on double chip PWM control, and the control circuit and the main circuit are explained in detail. The paper concludes with the proposal of a prototype that meets the expected experimental results.

In this work, the analysis of a CD-CD converter type Boost is presented. This converter works in Discontinuous Conduction Mode; In addition, the design of its control loops is performed, using an Average Current Mode control. The Boost converter is part of a photovoltaic generation system using solar panels. The photovoltaic system is established in a microgrid, with which the inverter works in grid mode and island mode. The main objective of the Boost convertor is to raise and regulate the voting from the solar panels to feed a single-bridge full-bridge inverter. The controllers designed for the boost converter are validated by simulation. The results obtained prove that the designed controller has an acceptable transient response to disturbances in the system input and adequately analyzing overdrafts and establishment times when disturbances are generated.

The conversion of A.C to D.C determines the distortion of the mains current A.C., which degrades the input power factor. The main reason for a poor power factor is the non-linear nature of the circuit. In this paper power factor is improved by using a basic boost converter and a control technique based on the fixed off time(FOT) approach .The traditional approach to the correction of the power factor in the boost converter is the continuous conduction mode with fixed frequency (FF-CCM) and the transition mode (TM) PWM (fixed connection time, variable frequency). In the first mode, the inductor operates in continuous conduction mode (CCM) and uses the average current-mode control mode; a complex technique involves a considerable number of components. The second method uses the more complex control technique of the peak current mode that makes the inductor work between continuous and discontinuous mode, which uses fewer components, unstable greater than 50% duty cycle and is more cost efficient. A third approach, the fixed off time (FOT) is gaining popularity which is conditionally stable for a duty cycle of over 50% and does not need compensation. The paper work carried out to use the power factor correction (PFC) based on DC-DC Flyback converter. To verify the design and operation of the circuit, the simulation is performed in PSIM .A prototype is developed and results are presented.

This paper investigates the interaction of fast-scale and slow-scale bifurcations in the boost converter under current-mode control operating in continuous conduction mode. Effects of varying some chosen parameters on the qualitative behaviors of the system are studied in detail. Analysis is performed to identify the different types of bifurcation. Boundaries of stable region, slow-scale bifurcation region, fast-scale bifurcation region, interacting fast and slow-scale bifurcation regions are identified.
