1. A power converter for converting an AC input of between frequency Fl at voltage V1 and frequency F2 at voltage V2 into a stable AC output of frequency F3 and voltage V3 comprises an AC/DC/AC/AC/DC converter (100) that converts, in only one direction, the AC input power (between F1, V1 to F2, V2) into a DC output DC1 as a function of the input (F1, V1 or F2, V2) and an inverter (200) that converts the DC output DC1 into an AC output AC2 of frequency F3 and voltage V3, wherein the inverter (200) comprises an oscillator, a wave form generator, a switching controller an output stage (202), and at least one electronic switch, said output stage (202) comprising two power switches (Q1, Q2), the power switches (Q1, Q2) having an ON position and an OFF position, wherein when both switches are in the ON position, short circuits are likely to occur, the wave form generator producing a positive pulse and a negative pulse, the positive pulse and negative pulse being separated by a gap to ensure that the two power switches (Q1, Q2) are never ON at the same time, wherein the inverter (200) comprises the wave form generator that comprises an oscillator and a Hex Schmitt trigger, and the power converter, which converts in only one direction, has a standby power consumption which does not exceed 0.5 Watt, and meets ErP and other ecodesign standards. |
