A Hitchhiker's Guide to Hysteretic Voltage Mode Control DC-DC Converters

Vishwanath D Tigadi


Abstract: Battery-supplied systems demand fast, efficient and compact power converters. Pulse-width-modulated (PWM) switch mode power converters (SMPS) are considerably efficient, but also slower, limited by their low band width. An improved Hysteretic pulse frequency modulated (PFM) nonlinear control method for DC-DC converters is illustrated in this paper. The basic disadvantages of linear control methods and their solutions are explained. The buck converter is taken as an example and Hysteretic voltage mode of control is implemented. The basics of hysteresis, working of hysteretic comparator, ease of implementation and working of control loop are explained and implemented using Texas Instruments Network Analyser (TINA). Advantages and disadvantages of Hysteretic control methods are discussed along with future scope.
