Abstract
An integrated power supply and modulator system includes integrated power supply and modulator system includes three subsystems: a switched-capacitor voltage balancer stage; a magnetic regulation stage; and at least one output switching stage. In one embodiment, the integrated power supply and modulator system further includes startup circuitry, feedback/feedforward circuitry and control circuitry.
Claims17
An integrated power supply and modulator system comprises:
- a magnetic regulation stage having an input adapted to receive an input signal and a plurality of outputs;
- a switched-capacitor voltage balancer stage having a plurality of inputs and a plurality of outputs with each input of said switched-capacitor voltage balancer stage coupled to a corresponding one of the plurality of outputs of said magnetic regulation stage;
- and
- at least one output switching stage having a plurality of inputs and at least one output with each input of said output switching stage coupled to a corresponding one of the plurality of outputs of said switched-capacitor voltage balancer stage.
1 more element
An integrated power supply and modulator comprising:
- a magnetic regulation stage, a multi-output switched-capacitor stage, and an output switching stage, wherein:
- said magnetic regulation stage is configured to draw charge from an input and provide charge to at least two input terminals of said multi-output switched capacitor stage;
- said multi-output switched capacitor stage is configured to accept charge from said at least two input terminals and redistributes charge to maintain a substantially ratiometric set of voltages between individual capacitor terminals and a reference potential;
- and
- said output switching stage comprises at least one switch to select from among at least two voltages of said ratiometric set of voltages of said multi-output switched-capacitor stage for provision to an output.
