    摘要： A primary side resonant circuit is formed by a primary side resonant inductor and a primary side resonant capacitor, and secondary side resonant circuits are formed by secondary side resonant inductors and secondary side resonant capacitors. Mutual inductances are formed equivalently through magnetic field resonant coupling between a primary winding and secondary windings, and a multi-resonant circuit that includes two or more LC resonant circuits is formed by a primary side circuit and a secondary side circuit. Electric power is transmitted from the primary side circuit to the secondary side circuit; resonant energy that is not transmitted from the primary winding and, of energy which the secondary winding has received, resonant energy that is not supplied to an output are each retained in the multi-resonant circuit; and, at the secondary side, the resonant energy is retained in a current path in which a rectifying element is not formed in series.

    摘要： A method for controlling a switching power converter which includes a central capacitor exchanges charge between the capacitor and plural nodes of a first terminal, and then transfers the charge between the capacitor and plural nodes of a second terminal. The charge interchanged between the capacitor and the nodes establishes the amount of power transferred during each cycle. The charge which is interchanged is controlled by selecting the electrical phase between the currents drawn from the nodes and the voltages at the nodes.

    摘要： A converter has a resonance circuit with an auxiliary valve (18), an inductor (17) and capacitive members (15) for assisting the commutation of the converter. A control arrangement (24) is adapted to control turning-on and turning-off of controllable semiconductor devices of the main valve of the converter and controllable semiconductor components of the auxiliary valve. Means are arranged for measuring the current in the phase output (10) of the converter. When carrying out two subsequent commutation processes for changing the phase potential on the phase output from the potential of a first of the poles of a direct voltage side of the converter to that of a second of the poles and then back to the one of the first pole the second commutation process is started before the first one has been completed.

    摘要： The present invention discloses a power conversion apparatus comprising a control circuit for generating a switching signal at the timing allowing soft-switching to be achieved, and free from any occurrence of ripple. The power conversion apparatus includes a first main switch (Q1) and a second main switch (Q2) which are connected in series with each other. One of the ends of the first main switch is connected with the positive side of a DC power supply, and one of the ends of the second main switch is connected to the negative side of the DC power supply. A diode (D1, D2) is connected in parallel with each of the main switches so as to become reverse biased with respect to the DC power supply. A main-switch snubber capacitor (C1, C2) is connected in parallel with each of the main switches. A load is connected with the junction between the pair of main switches, and the main switches are controllably switched according a switching signal from a control circuit to generate an output. A first auxiliary resonant circuit including serial-connected first and second auxiliary switches (Q3, Q4, Q5, Q6) and a resonant inductor (L1) connected in series with the second auxiliary switch is connected with each of the positive side of the DC power supply and the junction between the two main switches. A diode is connected to each of the first and second auxiliary switches so as to become reverse biased with respect to the DC power supply. The control circuit provides a turn-on signal to the first and second auxiliary switches according to a voltage signal as an input representing the voltage across each of the main switches and auxiliary switches from voltage detecting means before a turn-on signal as the switching signal is provided to the first main switch.
