ABSTRACT:
A switch mode power supply is disclosed having a pair of switch mode power supply sections which are maintained precisely 180.degree. out of phase and precisely matched in duty cycle. The phase locking of the switch mode power supply sections produces an output voltage which is substantially free of harmonics which requires greatly reduced filtering. A phase lock loop is provided for controlling the phase and duty cycle between the first and second sections of the switch mode power supply.
