Abstract

The present invention discloses a tower conberter with Phase-locked loop control in which the operating frequency of the circuit can track the resonant tank's resonant frequency by phase-locked loop (PLL) control to get the maximum output voltage gain. The present invention measures the voltage and phases of two points in a half-bridge converter by a phase detection module, locks the result by a phase-locked loop control circuit, and outputs a frequency signal to the half-bridge converter. Meanwhile, a current regulator circuit receives a feedback signal of a load from a current feedback module and makes the phase-locked loop control circuit control the output current to adjust the voltage gain.
