| Abstract(in English) | This paper presents new approarches to creating high-performance control systems for DC-DC converters (switching regulators) targeted for microprocessors power supply applications. Microprocessors power supply circuits demand both low-ripple-voltage in the steady state (stability) and fast response for large load changes. However, since in general stability and fast response are trade-off in control systems, it is difficult to satisfy both simultaneously with conventional approaches. (i) First we propose a completely different method which uses a variable inductor and a variable capacitor inside the regulator; the inductor and capacitor values are automatically varied so that they are large in the steady state to minimize ripple, and small for fast response when the load current changes rapidly. The variable inductor can be realized with parallel or series inductors connected a MOSFET switch. Also the variable inductor as well as the variable capacitor may be realized with MEMS (Micro Electro Mechanical Systems) technology. The load regulation detection circuit (which senses load current change) uses a transformer, a diode-bridge and an operational amplifier. (ii) We also propose to use a servo control technique in a conventional PWM controller. We have performed SPICE and CoventorWare simulation, and examined the effectiveness of the proposed methods. |
