A 3 phase semiconverter when supplying a certain load has a rectification efficiency of 0.6 and transformer utilisation factor of 0.35. When a 3 phase full converter is supplying the same load

• rectification efficiency will be more than 0.6 and TUF will be more than 0.35
• rectification efficiency will be more than 0.6 but TUF will be less than 0.35
• rectification efficiency will be less than 0.6 and TUF will be less than 0.35
• rectification efficiency will be less than 0.6 but TUF will be more than 0.35
