Power electronics design: buck, buck-boost, flyback, LLC and dual active bridge converters, power inductors, transformers and Litz wire, current-mode control and input filter stability, PWM methods, inverter losses with heatsink sizing, and a welding inverter. Each calc shows its method and published sources.
Wired White v2 Legen Sie einen modularen SST von Mittelspannung auf 800 V DC aus, vergleichen Sie vier SiC-Spannungsklassen und stellen Sie detaillierte CHB-, DAB- und Transformatorverluste einer konventionellen Wandlungskette gegenüber.
Wired White v2 Compare ANPC zero-state commutations, balance six-switch leg losses, and track transistor and diode junction temperatures through a low-frequency heavy launch.
Wired White v2 Calculate SiC MOSFET conduction, switching and dead-time losses over EPA UDDS, launch or locked-rotor stall. Track all six junction temperatures, peak temperature and thermal swing.
Wired White v2 Compare interleaved and grouped PCB windings using layer MMF and Dowell resistance. Calculate harmonic copper loss, leakage inductance, and iGSE core and total loss.
Wired White v2 Size the flying capacitor of a three-level inverter, predict natural balancing from switching harmonics and load impedance, and animate phase-shifted PWM.
Wired White v4 Compare VFD cable reflections and dv/dt filters with motor RPDIV and IEC insulation stress categories. Explore peak voltage, rise-time reserve and electrical life sensitivity.
Wired White v2 Size a two-switch forward welding inverter: transformer turns and copper, output choke, switch currents and losses, mains demand, and the arc load characteristic.
Wired White v3 Size the slope compensation and design a Type-II voltage loop for CCM buck, boost and flyback converters. Inspect sampled-data peaking, all gain crossings, Bode plots and a linear load-step estimate.
Wired White v3 Find a low-loss litz strand diameter and count for your winding window. Compare equal-copper solid wire and foil, including skin effect, proximity effect and current harmonics.
Wired White v3 Optimize TPS timing for minimum RMS current or circulating backflow with both bridges screened for ZVS. Compare SPS across bidirectional power, including an 800 V V2G preset.
Wired White v3 Check whether an LC input filter threatens converter stability. Compare RC and RL damping, two-stage filters, ripple attenuation, losses and small-signal transients.
Wired White v3 Size an LLC tank, compare FHA with exact PO/NP gain, and check ZVS charge margin and component stress for half-bridge or full-bridge operation.
Wired White v2 Estimate IGBT inverter losses and heatsink requirements including base spreading. Compare footprint and thickness effects on resistance and hot-spot temperature.
Wired White v2 Size or check a flyback transformer in DCM or CCM. Calculate inductance, turns ratio, peak and RMS currents, device voltage stress, winding estimates and an RCD clamp.
Wired White v2 Size a gapped ferrite inductor and check peak flux, copper loss and iGSE core loss. Compare air-gap and ripple-duty tradeoffs with published ferrite baselines.
Wired White v2 Size mains and ferrite bridge transformers with turns per volt, peak flux, window fill, copper and core losses, and temperature rise. Includes traceable loss models and winding checks.
Wired White v2 Compare SPWM, SVPWM, THIPWM and DPWM0–3. Animate the space-vector hexagon, inspect seven-segment switching and dwell times, and compare current ripple and relative switching loss.
Wired White v2 Design a non-inverting four-switch buck-boost power stage. Check CCM/DCM operation, inductor and capacitor sizing, RMS and peak stresses, and optional iGSE core loss.
Wired White v1 Size the inductor and output capacitor of a continuous-conduction buck converter and inspect its triangular inductor current.
