摘要： A bidirectional DC to DC power converter includes two DC sources, two inductors respectively connected to the two DC sources, a first switch and a second switch respectively connected to the two inductors, two capacitors respectively connected to the two switches, and a third switch connected between the two inductors. The first, second and third switches are respectively connected reversely with a diode in parallel. When the third switch is alternately turned on and off and the first and second switches are always turned off, the power converter operates as a boost power converter and electric energy flows from the two DC sources to the two capacitors. When the third switch is always turned off and the first and second switches are synchronously turned on or off, the power converter operates as a buck power converter and electric energy flows from the two capacitors to the two DC sources.

摘要： A backup power supply system supplies power from a first ac power source in normal condition. Once the first ac power source is abnormal or fails, the system automatically turns off the first ac power source and turns on a second ac power source with null transfer time. When the first ac power source is normal, a dc/ac power inverter is controlled to supply an approximately null current such that a mechanical switch is allowed to be closed and no circulating current is generated between the first ac power source and the dc/ac power inverter. Since the mechanical switch is continuously closed, and requires no switching operation, the backup power supply system can supply the backup power with a null transfer time.

摘要： An active power conditioner, connecting with a load and a power source in parallel, includes a DC power capacitor, a power converter, a high-frequency filter and a control circuit. The control circuit detects the voltage of the DC power capacitor and the current of the power source, thereby performing a closed loop control to stabilize the voltage of the DC power capacitor and performing a feed forward control to generate a driving signal for driving the power converter. The power converter actuates the DC power capacitor to supply a current via the high-frequency filter to reduce the reactive and harmonic components of load current. The load is converted to the linear resistance characteristic, observed from the power source side.
