Fundamental of power electronics: In a certain application, an unregulated dc input voltage can vary between 18 and 36 V. It is desired to produce a regulated output of 28 V to supply a 2 A load. control circuit automatically adjust D to maintain the constant output voltage and current. All ideal components. Hence, a converter is needed that is capable of both increasing and decreasing the voltage. Since the input and output voltages are both positive, converters that invert the...

Is N N Vo V's Vo Vs LOAD LOAD Figure 1 It has been shown in lectures that from the equality of power generation and power consumption, and as far as the average input/output voltages and currents are concerned, the buck and boost converters' operation in CCM (continuous current mode) are similar to the operation of the ideal AC transformers. So these converters may be considered as "ideal DC transformers". A buck converter operates with a duty cycle D 0.4,...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
