Abstract

It's best to use direct current power. Even at a 50% duty cycle, Power Electronics circuits can achieve a high level of efficiency and power density. DC-to-DC devices can provide higher output voltages, but the voltage cannot be controlled in the conventional manner. To control the output voltage, we advocate the use of active power filters and rectifiers known as active boost rectifiers (ABR). Since pulse-based switch control is required for all activities, the suggested rectifier is essentially a hybrid of a traditional diode rectifier and a bidirectional switch. The output voltage can be changed by adjusting the phase difference between the primary and secondary sides during the switching process. A family of soft-switching devices is possible thanks to the a-b active boost rectifier. Gentle switching continuous conduction mode of the converter allows for zero voltage switching on both the primary and secondary sides. Zero current switching on the primary side and zero voltage switching on the secondary side are both possible when the converter is operating in its discontinuous conduction mode. If the diode ever has trouble with reverse recovery, an active boost rectifier can be used to boost its output. To verify the efficacy of the current concept of this ABR and converters, the examination looks at the full bridge converter outfitted with a doubler diodes filter, dissecting its working principles of voltage conversion ratio and output features. The simulation results for the feasibility and effectiveness are presented in this investigation.
