Abstract

A bridgeless boost resonant converter with a hybrid pulse width modulation technique is mainly used for the application in power supplies and battery chargers. Especially in Continuous Conduction Mode (CCM) It has two active switches: a pulse width modulation switch and a hybrid modulation switch, with both switches' gates connected. There is no need for an extra circuit to gauge the AC input-line cycle activity since a pulse width modulation switch and a hybrid modulation switch are coupled together. The Inrush current can be limited by incorporating the PWM switches (especially while operating at a maximum duty cycle) by gradually increasing the voltage. Generally, the Totem pole power factor correction (PFC) is a popular topology as it uses different circuits for the correction of the power factor but HRPWM is chosen over the Totempole PFC because of the pulse width modulation operation will eventually reduce the reverse recovery losses of the diodes. The resonant tank components are extremely tiny. Can quickly turn off the di/dt of the output diodes during resonance operation to reduce reverse recovery losses and the electromagnetic interface. The proposed design is utilized to make lightning and surge protection systems simple to implement, and we can also employ zero voltage switching to reduce switching losses and increase efficiency.
