Abstract
An inverter for direct current power generation is shown in which both voltage regulation and logical control of the output are achieved by digitally controlling the application of clock signals to the inverter circuit. A standard clock source is used to drive the inverter and digital circuitry, timed from the same clock source, is used to control the gating of clock pulses to the inverter. Entire clock pulses including both positive going and negative going transitions are blocked so as to preserve the balanced excitation of the inverter transformer. Logical control signals can also be used to disable the application of clock pulses.
Claims5
A digitally-controlled inverter comprising:
- a source of clock pulses,
- a transformer responsive to said clock pulses,
- a rectifier connected to the output of said transformer,
- means for inhibiting only one or more successive full cycles of said clock pulses, and
- means responsive to the output of said rectifier for controlling said inhibiting means.
A regulated inverter comprising:
- a clock pulse source,
- a transformer responsive to said clock pulse source,
- a rectifier connected to the output of said transformer,
- a source of reference voltage,
- a comparator for comparing said reference voltage and the output of said rectifier, and
- means responsive to said comparator for blocking entire clock pulses from said source.
