    • This invention relates to an apparatus and a method for multistage hierarchical pyrolysis and gasification of solid fuels. The apparatus comprises a feeding device 1, a multistage fluidized bed reactor 6, a residual discharging valve 9, a cyclone 10 and a condenser 11. A gas inlet is provided at the bottom of the multistage fluidized bed reactor 6 and a number of stages of fluidized beds 3 are provided within the multistage fluidized bed 6, wherein the fluidized beds 3 are separated by a number of perforated distributors 5. The top stage fluidized bed 3 is connected with the feeding device 1 and the coal fed thereto is heated by char obtained from pyrolysis in this stage and the mixture of high temperature ascending pyrolysis and gasification gas to undergo pyrolysis reactions at low temperature, thereby to obtain solid particles after preliminary pyrolytic process. The solid particles flow downwards through an overflow standpipe 4/the perforated distributor 5 to the next stage of the fluidized bed and then are pyrolyzed through being heated by char and the mixture of pyrolysis and gasification gas. The solid particles in turn pass into the next stage of the fluidized bed and finally enter into the bottom stage fluidized bed to undergo gasification reactions. More light fractions in tar can be produced using the present apparatus and method.

    • A power converter including a resonant circuit is controlled by pulse width modulation (PWM) of a switching circuit to control current in the resonant circuit near the frequency of the resonant circuit (a null-immittance criterion) in order to control current and voltage at the output of the resonant circuit. Further control of voltage can be performed by PWM of a switching circuit at the output of the resonant circuit such that centers of the duty cycles of respective switches for the output of the resonant circuit are substantially synchronized and substantially symmetrical about centers of said duty cycles of respective switches at the input of the resonant circuit. Thus, operation of the converter is substantially simplified by using only PWM, a wide range of input and output voltages can be achieved and the converter circuit can be configured for bi-directional power transfer.
