Abstract: An electric circuit for the conversion of a multiplicity of commercial power voltages to a predetermined supply voltage which is independent of the respective commercial power voltage, for a device with high electrical power requirements of high output, in the range up to 40 kW, such as a bobbin winding machine. The circuit contains a rectifier stage for generating a primary intermediate circuit DC voltage, a converter stage with power switches for generating a rectangular AC voltage, a high-power transformer with a connected secondary control circuit and a control stage which triggers the power switches at zero voltage in a phase-shift mode with a variable frequency and pulse width of the rectangular AC voltage as a function of the input voltage of the rectifier stage, the transformer primary winding current and both the voltage and the current in the secondary intermediate circuit.
