Abstract: A soft-switching bi-directional power converter includes a main inductor, a bi-directional switch module, a first switch module, a second switch module, and a control unit. The bi-directional switch module has a bi-directional switch and a resonance inductor. The first switch module has a first switch and a first resonance capacitor; the second switch module has a second switch and a second resonance capacitor. When the bi-directional switch is controlled to occur a resonance of the resonance inductor and the first and the second resonance capacitors so that a voltage of the first resonance capacitor drops to zero, the first switch is turned; when the bi-directional switch is controlled to occur a resonance thereof so that a voltage of the second resonance capacitor drops to zero, the second switch is turned on. Accordingly, the power converter can implement the bi-directional soft switching function.

Abstract: A power converter includes a primary-side switching circuit, a resonant circuit, a transformer including primary and secondary windings, a secondary-side rectifying circuit, voltage and current sensing circuits, and a processing circuit. The primary-side switching circuit controls switches to be on or off based on a pulse signal to convert an input voltage to a square wave signal. The resonant circuit is coupled to the primary-side switching circuit and receives the square wave signal to provide a primary-side current. The primary winding is coupled to the resonant circuit. The secondary-side rectifying circuit is coupled to the secondary winding and rectifies the secondary ac signal output by the secondary winding and outputs an output voltage. The voltage and current sensing circuits detect the voltage and current of the primary winding and output voltage and current sensing signals. The processing circuit outputs the pulse signal according to the voltage and current sensing signals.

Abstract: A charging apparatus with dynamical charging power is configured to charge an electric vehicle. The charging apparatus includes a main power conversion unit, an auxiliary power conversion unit, and a control unit. The main power conversion unit receives an AC power and converts the AC power into a main output power. The auxiliary power conversion unit receives an auxiliary DC power and converts the auxiliary DC power into an auxiliary output power. The control unit controls maximum output power of the main output power to be an upper-limit output power value. When a charging power value of charging the electric vehicle is greater than the upper-limit output power value, the control unit dynamically controls the auxiliary output power according to a power difference value between the charging power value and the upper-limit output power value.
