FIELD: lighting.
SUBSTANCE: power supply signal generator includes rectifier module (10) for rectification of received alternating voltage (VS) of supply, load contact terminals (20) for providing voltage (VL) and/or current (IL) of excitation for excitation of said load, capacitive accumulator module (30) connected between mentioned rectifier module and load contact terminals for electric energy storage provided by said rectifier module, and provision of electric power in defined load , and bridge switching module (40) connected between above mentioned rectifier module and load for switching capacitive accumulator module on load current path from defined rectifier module into said load contact terminals with required polarity and for switching of said capacitive accumulator module from said load current path.
EFFECT: higher power factor, reduced losses and output light flicker.
