The full-wave rectifier circuit rectifies the three-phase AC power to a DC power.

The power transistor array is connected to the full-wave bridge rectifier.

A control circuit is also provided to allow switching the associated rectifier circuit of the thermoelectric system from full-wave rectification to half-wave rectification.

The apparatus includes a full-wave bridge rectifier, a power transistor array, and a controller.

The dimmer may also be used to control general household devices containing a front-end full wave bridge rectifier.

The full-wave bridge rectifier is configured to receive an AC input from the power source.

For the power supply, a full-wave rectifier (bridge of diodes) may be arranged between the two contacts (CLK; I/O).

  It is determined whether the output voltage of the full-wave rectification circuit (11) is not smaller than a predetermined value.

This effect is obtained by means of a perceptual sound contrast (a two-fold alternance of timbre and intensity) intended to “surprise” the ear.

The bidirectional switch circuit turns on/off the input of each phase input from the three-phase AC power supply to the full-wave rectifier circuit.

The secondary circuit (5) has a capacitor connected in series with the secondary winding (3) or a full wave rectifier (6, 7).
