摘要： In a regulated, resonant inverter system for supplying direct current to a load wide operating frequency swings required to compensate for output variations are eliminated by selectively switching combinations of binary weighted parallel resonant inverter stages (ST-1 to ST-4). The stages are tuned to the same frequency, but each stage has a different power capability determined by the square root of the ratio C/L, where C is the resonating capacitance (46-1 to 46-4) and L is the magnitude of the resonating inductor (42-1 to 42-4 and 44-1 to 44-4). For a desired output condition, a feedback circuit (19-27, 60) selects a stage or a combination of stages and controls the operating frequency thereof so that the operating frequency remains high at all power levels.

摘要： A converter includes an input capacitor, a primary-side switch circuit, a magnetic element circuit, a secondary-side switch circuit, and an output capacitor. The magnetic element circuit includes a transformer and an inductor. The input capacitor is configured to receive an input voltage. The primary-side switch circuit is coupled to the input capacitor. The magnetic element circuit is coupled to the primary-side switch circuit. The inductor is a leakage inductor of the transformer or an external inductor coupled between the transformer and the primary-side switch circuit. The secondary-side switch circuit is coupled to the magnetic element circuit. The output capacitor is coupled to the secondary-side switch circuit. The input capacitor and the inductor generate an oscillating current. The primary-side switch circuit is switched at an adjacent region of a wave trough of the oscillating current.

摘要： An inductive boost circuit (51, 52) is added in paralell with an inverter (11) to increase current to an EL lamp (27). The inverter and the boost circuit each include a switching transistor. The switching transistor (52) in the inductive boost circuit may be matched to the switching transistor (21) in the inverter and may be driven synchronously with the switching transistor in the inverter.

摘要： A known power source (S) comprises input (G1, T) and output (G2, T) converting components with LT and MT converting cells (CC), T >/= 0 galvanodecoupling bifilar converter transformers (GTR) (2, 9, 12, 16, 20, 22, 24, 26 ,29). Lo >/= 2, Mo >/= 2 CC are based on "Motovilov's transformers" and on direct current power transformers (TM), each comprising two symmetrical groups of windings and rectifiers, in particular, for pulse control of the direct current of the windings of TM. To decrease the influence of the pulse and alternating current in the windings of TM and GTR on leakage inductance Ls of the windings, and to consequently improve the frequency qualities of S, the decoupling and converting functions in S are distributed between GTR with a gain factor of 1, having correspondingly reduced Ls, and the TMs introduced for that purpose into the converting components (G11 and G21) intended to function on direct current (2, 9, 22, 24, 29) whereas Lo and Mo of CC with TM functioning on the basis of direct current are interconnected according to a multicell circuit which is characterized by the number of voltage levels at the output of the circuit equal to Y = 1 + 2 at the total power of all CCs equal to P /= 2 and M1 >/= 2 of CC according to said multicell circuit (12, 16).
