The objective of this paper is to present a family of PWM dc-dc converters that achieves ZVS (Zero Voltage Switching) for the main switch and ZCS (Zero Current Switching) for the auxiliary switch using a new configuration of the auxiliary circuit cell. It is shown that the proposed auxiliary circuit cell can be used in all three basic dc-dc converters - buck, boost and buck-boost - to transform a...
This paper presents the design of a single-inductor regulated multiple-output (SIMO) buck converter with interleaved switched capacitor outputs. A small signal analysis of the buck converter using state space averaging technique is carried out. A compensating network and novel control logic are designed to minimize effects of cross regulation and load transient in the three-coupled outputs. In view...
The objective of this paper is to propose a simple digital current mode control technique for dc-dc converters. In the proposed current-mode control method, the inductor current is sampled only once in a switching period. A compensating ramp is used in the modulator to determine the switching instant. The slope of the compensating ramp is determined analytically from the steady-state stability condition...
