Design of class DE amplifier with any output Q, any duty ratio and switch on resistance <Abstract> This paper presents a new design procedure for class DE amplifier. And the designs of class DE amplifier with any output Q, any duty ratio, and switch on resistor are carried out. The feature of the proposed design procedure is that the waveform equations never be needed. The design procedure requires only circuit equations and the design specifications. When circuit equations are derived, the other procedures for computations of design values are carried out with aid of computer. Therefore, it is possible to design class DE amplifier with any conditions, namely, with any output Q, any duty ratio, switch on resistance and so on. We can denote the design values and output capabilities of class DE amplifiers with any output Q, any duty ratio, and switch on resistance by using proposed design procedure. By carrying out the circuit experiment, we denote that the experimental result agrees with the calculation result quantitatively, and show the validity of the proposed design procedure. |
