Abstract
A power supply includes an inverter configured to convert direct current (DC) power into alternating current (AC) power, an impedance matching circuit configured to supply the AC power to a load, and a controller configured to detect a delay time of an output voltage and an output current output to the impedance matching circuit and the load and to adjust a frequency of the output voltage according to the detected delay time.
Claims4
A power supply comprising:
- an inverter configured to convert direct current (DC) power into alternating current (AC) power and provide an output voltage and an output current;
- an impedance matching circuit configured to transfer the AC power to a load;
- a controller configured to detect a delay time of the output voltage and the output current, adjust a frequency of the output voltage according to the delay time, and output one or more switching signals to the inverter;
- and
- a phase information detection part coupled between the inverter and the impedance matching circuit that detects phase information of the output current and provides the phase information to the controller, wherein:
- the controller detects the delay time between the output voltage and the output current using the phase information and at least one of the one or more switching signals,
- the inverter comprises an inductor coupled between nodes on which the output voltage is output, and
- the controller adjusts the frequency of the output voltage until a phase of the output voltage and a phase of the output current are equal.
