Hi,
My name is John Lester Soronio. I am a senior electronics design engineer and currently working as project lead of many power solutions released in the market involving AC-DC power supply, DC-DC power supply, DC-DC converter (buck, boost, buck-boost, flyback, forward, resonance, etc), chargers and adapters. I am in this business for more than 10 years. I am working full time at Artesyn Embedded Technologies; formerly Emerson Network Power.
Summary of Capabilities:
1. Schematic design and PCB layout
2. AC-DC power supply design, switching and linear, multiple outputs or single, trimmable or fixed
3. DC-DC power supply design, boost, buck, buck-boost, etc...
4. Offline AC-DC adapter design
5. Charger design with constant current and constant voltage, AC-DC for phones and other applications
6. Charger design with constant current and constant voltage , DC-DC for Li-Ion, Li-Poly, LiFeP04, Lead acid and so on
7. LED lighting related applications
8. Solar panel energy harvesting and charging systems
9. Switching converters such as buck, boost, buck-boost, flyback, forward, LLC, half bridge etc
10. Amplifiers, filters, switch
11. MCU, DSP and digital circuits
12. Schematic and PCB using eagle
13. Simulations using LTSpice, Matlab, Simulink, Simetrix and Simplis
14. Design analysis and computations using Mathcad
15. Control system design, type 1,2,3 and PID using spice, SISO tool in Matlab or Simulink control design
