Expert in Analog Circuits and Power Electronics
AC TO DC CONVERSION AND CONVERTORS. Expert's background includes all types of rectifiers and filters, including high frequency, low loss conversion, as well as multi-phase conversion.
AMPLIFICATION; DC AMPLIFIERS; DIFFERENTIAL AMPLIFIERS. Expert has experience with solid state DC and AC amplifiers up to 100MHz, including selective amplifiers of low pass, high pass, or band pass type.
ANALOG CIRCUITS; ANALOG CIRCUIT DESIGN. This includes linear and non-linear amplifiers, multipliers, flip-flops, time delay, signal generators, and active RC filters, as well as passive filters of all types and characteristics. Expert has had experience with all of these.
DC TO DC CONVERSION. Expert has worked with moderate to high frequency conversion (from a few KHz to MHz) of the buck, boost, flyback, forward, push pull, and resonant types, including design, analysis, and compensation for specific characteristics of bandwidth, regulation, and efficiency.
ELECTRONIC ENGINEERING AND ELECTRONICS. Expert has been involved in the design of vacuum tube and solid state electronics circuits.
FEEDBACK. Expert understands negative and positive feedback systems for control, regulation, signal generation, and filtering functions. His design specifications can be of the steady state characteristics, or transient response of the system.
SWITCHED MODE POWER SUPPLY; Expert has knowledge of switched mode power supplies, AC to DC, DC to DC, and DC TO AC switched mode supplies of the buck or boost type at moderate to high frequency, (kHz to MHz) using flyback, forward or push-pull and resonant conversion methods for regulation, stability or transient response, and efficiency of conversion.
DIRECT-CURRENT TO ALTERNATING-CURRENT CONVERTER. Expert is experienced with low-voltage DC to AC converters of 25V to 150V RMS, typically at frequencies of 60Hz to 200kHz, both sine wave and pulse wave.
