PRACTICAL REALIZATION OF IDEAL DIODE FULL-WAVE RECTIFIERS


Abstract

This paper discuses practical realization of full-wave rectifiers made of electronic diodes for high current bipolar electronic loads. The presented solution minimizes the voltage drop and nonlinearity of loads in the region of low voltages. Compared to standard or Schottky diodes, electronic (also referred to as ideal) diodes exhibit very low voltage drop and power dissipation. In the full-wave rectifier, MOSFETs with very low RDSon (low units of milliohms) are used. Ideal rectifiers have been traditionally used as structural elements in switched power supplies; they are often applied in low dissipation power switches and started to be utilized as full-wave rectifiers.
