PWM buck convertersingle-loop controlvoltage-mode controlSummary This chapter explores voltage-mode control of the PWM buck converter. A buck PWM converter with negative feedback is illustrated. This control scheme is called voltage-mode control because the duty cycle is proportional to the control ...
This article mainly focuses on the development and implementation of a buck converter with a sliding mode voltage controller, to achieve the stable desired voltage output. Firstly, based on Lyapunov stable analysis, the controller is proposed to enforce the system trajectory from the arbitrary point ...
This example shows the operation of a voltage-controlled buck converter. Description The DC motor is fed by the DC source through a Buck Converter block implementing an IGBT/diode pair. The motor drives a mechanical load characterized by inertia J, friction coefficient B, and load torque TL. ...
Closed-loop small-signal characteristics are given for a voltage-mode-controlled PWM buck DC-DC converter with a proportional controller for continuous conduction mode (CCM). All parasitic resistances are taken into account. The following characteristics are presented at different values of the equivalen...

A new digital controlled, bridgeless ac/dc buck converter that operates in discontinuous-input-voltage mode (DIVM) is presented. It has inherent power factor correction property and draws continuous input current during conduction period with a constant duty cycle. In addition, the efficiency of the...
1. Introduction to Synchronous Buck Converter with Voltage-Mode ErrorAmplifier A buck converter with voltage-mode control and voltage-mode error amplifier can be stabilized with a proportional-integral (PI) type of compensator. However, to have high performance a more sophisticated compensation network...
For the voltage mode buck converter, only one ADC conversion is required. This is the output voltage rail that is regulated. Therefore, the number of conversions is currently set to 1. The ADC conversion is configured by expanding the Rank subcategory. Set the Channel to Channel 4. HRTIM M...
