  • Self-adjusting bleeder for a forward converter
    Patent number: 7863870
    Abstract: A switched mode power supply (SMPS) may be operated with uncoupled output inductors. Overvoltage produced by “low-load” conditions may be controlled through use of an adaptive regulating bleeder. The bleeder may comprise a shunt regulator and a power dissipation resistor connected in parallel with a load of the SMPS. As load on the SMPS is reduced below a predetermined level, the shunt regulator may begin to conduct. Current may pass through the power dissipation resistor. Power dissipation may occur at a rate sufficient to maintain continuous conductance through an output inductor of the SMPS. During normal load operation, the shunt regulator may not conduct and inefficient dissipation of power through the resistor may be avoided.
