Level Converter

The multi-level converter is one of the focuses in the current high-voltage high-power field of power conversion, and is found widely application in high power drive system. It generated so far for nearly three decades of history. During this period a large number of multi-level topology appeared, there are three most commonly used, which are diode clamped, capacitor and cascaded H-bridge. In this paper, the development of the multi-level converter is reviewed. The structure of three multi-level converter topologies are given, and then their advantages and disadvantages are given by analyzing and comparing their characteristics. Finally, a new modular multi-level converter (MMC) is introduced which is one of research focus of multi-level converter field at present. Its structure and working principle are described in detail. Multi-level converters will continue to be developed to meet the demand of high-voltage and high power applications.

Power Hierarchy

Giving thanks has multiple psychological benefits. However, within intergroup contexts, thankful responses from low-power to high-power group members could solidify the power hierarchy. The other-oriented nature of grateful expressions could mask power differences and discourage low-power group members from advocating for their ingroup interests. In five studies ( N = 825), we examine the novel idea of a potentially harmful side of “thanks,” using correlational and experimental designs and a follow-up. Across different contexts, expressing thanks to a high-power group member who transgressed and then helped undermined low-power group members’ protest intentions and actual protest. Thus, the expression of thanks can pacify members of low-power groups. We offer insights into the underlying process by showing that forgiveness of the high-power benefactor and system justification mediate this effect. Our findings provide evidence for a problematic side of gratitude within intergroup relations. We discuss social implications.

The Way

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.

Effect of Power on Moral Judgment

Experimenter Effects

Ambiguous effects of power on attributions of moral responsibility for an accident are interpreted to result from the intervening effects of need for power, which is aroused by the anticipation of exercising power over another. 160 subjects from introductory social psychology classes participated in a questionnaire-type experiment comparing effects of high/low carelessness, severe/minor consequences, and high/low power of the attributor in a 2 × 2 × 2 factorial design. In a follow-up experiment 30 subjects were assigned to conditions of high or low power, and their needs for power and moral attributions were measured. High power seemed to arouse need for power, which was curvilinearly related to moral judgments. Those high and low in need for power attributed more moral responsibility to the perpetrator of an accident than those with moderate levels of need for power. The results suggest complicated models of both moral judgments and experimenter effects related to the level or arousal of motivations.

Significant Mediator

Ingratiation refers to acts of flattery, typically given by a low-power person to a high-power one, performed to gain acceptance and approval. This study investigates ingratiation in the religious setting, asking whether people feeling high levels of guilt or shame tend to manifest such ingratiating behavior toward God. The study aimed to examine the mediating role of prayer in the relationship between guilt and shame and ingratiation toward God. A total of 148 respondents (80 women and 68 men) participated in the study. The Religious Ingratiation Scale, the Content of Prayer Scale, and the Guilt and Shame Proneness Scale were applied to the research. The results showed that feeling guilty increased the tendency to ingratiation toward God. Prayer was the significant mediator in this relationship. People high in guilt tend to flatter God by offering more adoration and fewer repine prayers.

The Other

Participants were randomly assigned to be high or low power and interacted with another who consistently cooperated, or consistently competed, or alternatively cooperated and competed. Results indicate that low power participants acted more cooperatively, were more attracted to, and wanted to facilitate the other's outcomes to the extent the other had cooperated; the cooperativeness of the high power participants was unaffected by the low power person's actions.
