Method and device for supplying consumers with more full-sinusoidally, variable amplitude AC voltage by means of an inverter in the known embodiment net-synchronouslyintermediate circuit smoothing and without power-factor-without correction, equipped with a current sensor, which detects the actual current flowing in the array, the optimum sinusoidal current curve determined and the effective value thereof is derived from the effective value and possibly additionally current harmonic waves determined the amount of. From the information from the information of the deviation and the at least a message can then settle the tax rate current harmonic waves, when certain limit values are injured, he can try a correction of the PWM signal to the second is to have to comply with can change to operate switch off Allow could bring about an improvement, for third he the output voltage, by more correction reserves, and as a fourth he dOLLAR A By. having the above-described additional devices it possible the use of a simplest inverter, any loads, in particular, however, non-linear loads such as error resilience [...], thereby extending the current rules for without PFC-Device on electricity grids current harmonic waves, at least as long, as the loads this. During a very long time, for example, form a very linear load [...] fail-safe for lighting devices. Only for the rare case that a lamp... |
