Question

3) The Figure shows the schematic of a Synchronous converter. The converter has the following requirements: 350V Vin: Vout 75V regulated Load power 200W Switching frequency: 750kHz Max. output ripple: 30mV 01 L1 Vin LC1 you 02 Vn 1. Calculate L1 and C1 2. What is a synchronous converter? Differentiate with a typical Buck converter

b}} A synchronous converter is asynchronous machine that converts alternating current to direct current, or vice versa. A synchronous converter in which motor and generator windings are combined on one armature and excited by one magnetic field is normally used to change alternating to direct current.
