DC-DC converter modules provide efficient power conversion and high power density. They integrate control circuits, magnetic components, switches, and packaging into a single component. One module has a power density of up to 120 W/in3. The document discusses DC-DC converter modules, their basic power train and circuits, and modeling tasks for their components like the transformer, choke coils, MOSFET switches, and output filters.
This document provides design details and simulation files for a boost DC/DC converter circuit using the NJM2377 PWM controller IC. It includes:

This document lists various simple electrical component models that are available in the PSpice and LTspice simulation programs, including DC-DC converters, inverters, power supplies, batteries, fuses, transformers, motors, and custom models that can be created by the user. It also notes that Simple Model is a spice model parameter base for creating custom models in the listed simulation programs.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like depression and anxiety.
This project envisages a Buck dc – dc
converter mathematical analysis and simulation. This power
regulator is made up of some vital circuit elements such as
inductor, freewheeling diode, filter capacitor and electronics
power switch. The circuit is analysed based on two modes of
operation namely: continuous current conduction mode and
discontinuous current mode. Ansoft Simplorer software is
used to carry out the circuit simulation under the two modes
of operation which aided in verifying the calculated results.
Both calculated and simulated waveforms are displayed. The
results obtained are very similar.
Here are the key steps in the simulation example:
1. Set PWM controller parameters: FOSC, VREF, VP
2. Set output voltage: Rupper, Rlower
3. Select inductor: L for CCM operation
4. Select capacitor: C, ESR for ripple requirements
5. Extract compensator parameters: C1, C2, R1, R2
6. Simulate and verify switching waveforms, efficiency
The example shows designing, simulating, and verifying the operation of the boost converter to meet the given specifications.
