Assignee: INNOMOTICS GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 8:
9. A power supply comprising:
an input stage configured to receive an input signal from a power source, wherein the input signal comprises an input frequency, wherein the input signal is a three-phase input signal and wherein the power source is a three-phase power source;
an output stage configured to provide output power based on an output signal, wherein the output signal comprises an output frequency; and
a controller configured to provide control signals to the output stage,
wherein the controller further comprises controls and a pulse-width modulation (PWM) module to generate the controls to modify the output signal,
wherein the controls modify the output signal by injecting a frequency component into the output signal having a phase-shift dependent on a load power factor to drive a single-phase load, and
wherein the injected frequency component is three times the output frequency of the output signal,
wherein the power supply further comprises the single-phase load, and
wherein the modified output signal drives the single-phase load that is insensitive to a distortion in the modified output signal.
