Abstract

The present invention discloses a power system, including a switching circuit, a resonant tank, a feedback circuit, and controller circuitry. The switching circuit including a first switch and a second switch provides a first AC signal. The resonant tank coupled to the switching circuit receives the first AC signal and generating a second AC signal for powering a load. The feedback circuit coupled to the load monitors an electrical condition of the load and provides a feedback signal. The controller circuitry coupled to the converter controls the switching circuit according to the feedback signal so as to control the power to the load. The controller circuitry is integrated in a first die. The first switch is integrated in a second die, and the second switch is integrated in a third die. The first die, said second die and said third die are mounted on and electrically interconnected to a platform compatible with through-hole technology. The platform and the resonant tank are further assembled on a printed circuit board. The power system is integrated with a control circuit, the switching circuit and the feedback circuit on a platform so as to improve the flexibility of design and application and the reliability of the power system.

Description

technical field [0001] The invention relates to a power supply system. Background technique [0002] A power system, such as an inverter system that converts DC power to AC power, includes a control circuit, feedback circuit, switching elements, and a resonance circuit. The traditional structure of the inverter system is a structure based on a chip (dice) or a structure based on an integrated circuit (integrated circuit; IC). [0003] In a chip-based architecture, discrete chips are individually packaged into discrete integrated circuits, which are then mounted on a printed circuit board. The control circuitry is integrated in a surface-mounted IC package. The switching elements are active semiconductor devices, and each switching element is integrated in a separate surface-mounted integrated circuit package. The feedback circuit includes discrete components such as resistors, capacitors, and diodes, also integrated in a separate surface-mounted integrated circuit package...
