Abstract
Low leakage current power supply methods, systems, and apparatus are described. In one example, a medical system includes a plurality of medical devices and a power supply configured to provide alternating current (AC) power to the plurality of medical devices. The power supply includes an input configured to receive AC power from an AC power source, an isolated switching power converter coupled to the input to receive the AC power and output AC power, a controller coupled to the isolated switching power converter and configured to control operation of the isolated switching power converter, and an output coupled to the isolated switching power converter to provide the AC power output.
Claims12
A medical system comprising:
- a plurality of medical devices;
- and
- a power supply configured to provide alternating current (AC) power to the plurality of medical devices, the power supply comprising:
- an input configured to receive AC power from an AC power source;
- an isolated switching power converter coupled to the input to receive the AC power and output AC power;
- a sensor coupled to the input and configured to generate a sensor output indicative of a first frequency of the AC power received from the AC power source;
- a controller coupled to the isolated switching power converter and the sensor, the controller configured to control, based on the sensor output, operation of the isolated switching power converter to output AC power at the first frequency;
- and
- an output coupled to the isolated switching power converter to provide the AC power output at the first frequency.
