    ABSTRACT: A companion paper (New and Wittey) describes a new Power Equipment Rack concept. The present paper describes the design of a SMPS for the new rack. The SMPS operates on 240V 50Hz s.p. A.C., producing a nominal 28A D.C. at a preset level between 52 and 58V D.C. The active element is a power transistor half-bridge switching the transformer primary winding at 20kHz between the centre tap of series connected capacitors across a D.C. link, using PWM for load-dependent regulation. The D.C. link is provided by a f.w. diode bridge across the line, feeding a small reservoir capacitor, topped up by a shunt-transistor (boost) converter giving line-dependent pre-regulation. The rectified transformer output (40kHz) after filtering for ripple and RFI may be used to provide an output of either polarity. A low power auxiliary inverter provides isolated supplies for the transistor base drives. The module is totally enclosed for better mechanical protection and freedom from RFI, and has a single full length `thermal wall' heat sink carrying insulated devices, which forms the mechanical `back bone' of the module. 95% of the drilling and tapping operations are carried out in this heat sink using a steel jig. Almost all interconnections are made using PCB tracks, leaving only a few wire links between PCB and devices. Overall efficiency is better than 90% at f.l.c. and the psophometric ripple is about 1mV. Line power factor is better than 0.97 and fold back current limit below 40V cuts the current back to 2.

    ABSTRACT: Emotional care is an important component of abortion services. Evidence-based counseling for other stigmatized and sensitive health issues may be informative for the improvement of abortion counseling. We searched the literature for practices used in emotional care for stigmatized and sensitive health issues. We made analytic choices for the selection of articles using the "constant comparative method," a grounded theory technique. We selected practices that were effective in supporting coping and improving psychosocial adjustment. Findings were synthesized and analyzed to draw evidence-based implications for abortion counseling. We uncovered nine practices used in emotional care for stigmatized and sensitive health issues that have been shown to support coping or improve psychological adjustment. The techniques and interventions identified were: self-awareness assessments, peer counseling, decision aids, encouraging active client participation, supporting decision satisfaction, support groups, Internet-based support, ongoing telephone counseling, and public artistic expression. A variety of patient-centered, evidence-based interventions used for other health issues are applicable in emotional care for abortion. Evaluation of these practices in the abortion counseling setting can determine their appropriateness and effectiveness. Abortion care providers may be able to integrate additional patient-centered practices to support coping or improve psychological adjustment after abortion.
