  • Full range soft-switching DC-DC converter
    Patent number: 5875103
    Abstract: A soft-switching DC to DC power converter which minimizes switching losses from a no load condition to a full load condition while operating at fixed frequency. Output voltage control is achieved by controlling the phase angle between the two switching networks. High frequency transformer primaries are always excited with a square wave input voltage equal to ##EQU1## The power converter can be implemented with a single transformer. Moreover, the switch voltage never increases the input DC voltage from no load to full load. The power converter can be used in both low voltage high current applications and high voltage low current applications.

  • Bias power having a gapped transformer component
    Patent number: 5663873
    Abstract: A half bridge power converter which employs a gapped transformer which permits stable asymmetrical operation without the use of a separate choke arranged in parallel with the primary of the transformer. The half bridge power convert may include a small capacitor on its secondary side to cause a high ripple of the output current thereby permitting stable asymmetrical operation with smaller magnetizing currents.
