Definitions

  • Mains feedback affects the effect of non-sinusoidal consumer currents on the internal resistance (generator and cables) of the supply network, with the consequence of an undesirable voltage distortion (deviation from the sinusoidal form) of the mains voltage.
  • a high power factor ( ⁇ «1) reduces the reactive currents and thus the ohmic losses in the power lines of the power supply companies.
  • Consumers with non-sinusoidal, pulse-shaped current consumption are e.g. : TV receivers, HiFi devices, computers, measuring, control and regulating devices, dimmers for incandescent lamps, dimmable electronic transformers for low-voltage halogen incandescent lamps, simple electronic discharge lamp ballasts without passive or active harmonic limitation filters, as well as a large number of devices where phase or section controls with semiconductor components of power electronics are used.
  • Electronic HF dimmers for lamps reduce energy costs for lighting and protect the environment by reducing power plant emissions.
  • the mains voltage passes through a radio interference suppression filter 1 and a two-way rectifier 2 to a bridge circuit formed by four semiconductor switches S1 ... S4 (e.g. MOSFETs, IGBTs, bipolar transistors), in the diagonal (A ... B) of which high-voltage incandescent lamps and simultaneously low-voltage incandescent lamps can be operated via an HF transformer.
  • the four semiconductor switches are controlled by an HF generator with an integrated pulse width modulator (PWM) 4, which is supplied by means of a voltage converter 3.
  • PWM pulse width modulator
  • the pulse width modulator generates two square-phase signals with a variable pulse duty factor (PWM and PWM), the PWM signal triggering the switches S2 and S3 in phase and the inverted PWM signal triggering the switches SI and S4 in phase.
  • PWM and PWM variable pulse duty factor
  • the potential isolation for the semiconductor switches SI and S3 is done by the potential isolation components Pl and P3 (e.g. pulse transformers, optocouplers, high-voltage driver ICs, etc.).
  • the bridge diagonal results in an HF voltage (e.g. 40 kHz) modulated with the mains voltage (50 Hz) with a variable pulse width, which enables dimming.
  • the HF consumer current is also sinusoidally modulated in the bridge diagonal by high-voltage incandescent lamps Ll or HF transformers Tr with low-voltage incandescent lamps L2 connected on the secondary side with the great advantage that - even when dimming - the 50 smoothed by the radio interference suppression filter Hz mains current is largely sinusoidal and almost in phase with the mains voltage.
  • a highly simplified circuit (see Fig. 2) can be used, which also takes a largely sinusoidal current from the mains when dimming, which is in phase with the mains voltage.
  • Function groups 1 to 4 are identical to the circuit in FIG. 1.
  • a semiconductor switch S is sufficient to dim the incandescent lamp L (ohmic load).
  • the HF voltage is also modulated sinusoidally here and the filtered current taken from the network is again largely sinusoidal , ie this dimming circuit - like the circuit according to FIG. 1 - acts like a quasi "ohmic consumer" with respect to the supply network.

Abstract

Des gradateurs électroniques H.F. pour lampes à incandescence haute tension et basse tension présentent un très haut facteur de puissance et des harmoniques extraordinairement réduites du courant du secteur. La désignation usuelle de ces appareils permettant de faire fonctionner des lampes halogènes à incandescence basse tension était jusqu'à aujourd'hui 'transformateurs électroniques à gradation. L'avantage de l'invention est qu'elle permet de faire fonctionner en même temps, avec un gradateur H.F., des lampes à incandescence haute tension et basse tension.
