![]() ![]() ![]() That, com pared to a full-bridge converter, half the number of turns is required for the primary, but the power output Transformer to be supplied half the voltage of the rectified DC. The configuration of the capacitors, MOSFETs and transformer causes the MOSFETs work along with 2 capacitors to create the high voltage high frequencyĪC. A vital thing to remember is that in a half-bridge converter, the 2 To the ferrite transformer to step down the voltage to low voltage highįrequency AC which is then rectified to DC and filtered to provide clean DC This high frequency high voltage AC is fed Half-bridge converter, the line voltage is rectified and filtered and is thenĬonverted to high frequency with 2 MOSFETs – one in high-side configuration and The power range 100W to 500W, sometimes goin g up to even 1000W. The half-bridge topology is very popular for offline converters in Forums, I often find people asking for help in calculating the required turnsįor a ferrite transformer they are going to use in offline SMPS half-bridgeĬonverter s.
