This application note is intended as an addendum to the Design Reference Manual DRM064 ([1]) and describes implementation of an average current mode control of Power Factor Correction (PFC) on MC9S12E128. The DRM064 deals with the design of a Single Phase On-Line UPS using an MC9S12E128. It includes control of a power factor correction (PFC), a DC/DC step up converter, a battery charger, and an...

We calculate the first order maximal acceleration corrections to the classical electrodynamics of a particle in external electromagnetic fields. These include additional dissipation terms, the presence of a critical electric field, a correction to the cyclotron frequency of an electron in a constant magnetic field and the power radiated by the particle. The electric effects are sizeble at the f...

This paper introduces a high precise direct current (DC) negative high voltage power supply. The supply’s output voltage is 25kV and its maximal output current is 100mA. The power supply uses BOOST converter for power factor correction and voltage regulation. It converts DC to high frequency (HF) alternating current (AC) square wave with phase-shifted full bridge. The voltage of the AC square w...

Photovoltaic (PV) systems are increasingly used to generate electric energy from the solar irradiation incident on PV modules. The single ended primary inductance converter (SEPIC) is studied for maximum power point tracking and battery charging. High MPPT accuracy and high conversion efficiency can be achieved for different atmospheric conditions. A pulse-current-charging scheme with adaptive ...

Plug-in electric vehicles could offer flexibility for wind power and an attempt was made to quantify the effect with a power system model Wilmar. Wilmar simulates unit commitment and dispatch using mixed integer programming and includes wind power and load stochasticity as well as a module for plug-in electric vehicles. Forecast errors of wind power increase the need for balancing and ancillary...
