WebNov 4, 2024 · These are controlled by a pulse width modulation (PWM) controller to produce and regulate the desired output voltage. Figure 1: A typical DC-DC converter uses a PWM controller to drive half-bridge-configured power FETs. The controller adjusts the pulse width at the FET inputs to produce and regulate the required voltage at the output (VOUT). WebConverter systems invariably require feedback. For example, in a typical dc-dc converter application, the output voltage v(t) must be kept constant, regardless of changes in the input voltage v g (t) or in the effective load resistance R.This is accomplished by building a circuit that varies the converter control input [i.e., the duty cycle d(t)] in such a way that the …
