摘要:
The invention relates to a moveable holding device (1), comprising a moveable unit (30), a holder (10) that is attached to the moveable unit (30), a fixed guiding device (60) and at least one bistable spring (50) that is mounted with a first spring end (51) to the moveable unit (30) and with a second spring end (52) to the fixed guiding device (60). The at least one bistable spring (50) is deflected and pretensioned by moving the moveable unit (30) in longitudinal moving direction (35) in regard to the fixed guiding device (60) from a first stable end position (100, 120) to an unstable mid position (110) which is arranged halfway between the first stable end position (100, 120) and an opposing second stable end position (120, 100), where further longitudinal displacement in moving direction (35) between the unstable mid position (110) and the opposing second stable end position (120, 100) is spring drive actuated by the at least one pretensioned bistable spring (50).

A power inverter, such as a synchronous buck power inverter, that is configured with a high frequency switching control having a (PWM) controller and sensing circuit. Controller provides a low frequency oscillating wave to effect switching control on a synchronous-buck circuit portion that includes a plurality of switches to invert every half cycle of the frequency provided by controller. The inverting process thus creates a positive and negative transition of the oscillating wave signal. A low frequency switching stage includes a further plurality of switches configured to operate as zero voltage switching (ZVS) and zero current switching (ZCS) drives Charge on an output capacitor is discharged to zero on every zero crossing of low frequency switching stage and advantageously discharges energy every half cycle. During this discharge of energy, the zero crossing distortion in the low frequency sine wave is greatly reduced.
