... Application Note WARNING The HIP4082EVAL DC-AC Inverter contains HIGH VOLTAGE and is a potential shock hazard. USE CARE when DC power is connected. Introduction The advent of the personal computer (PC), has created the need for uninterruptible power supplies to insulate computers from line dips and temporary outages that plague PC reliability ...

... To minimize the size of the secondary filter, a 50% duty cycle square-wave was chosen for primary excitation. With a nearly constant, low-ripple voltage, secondary filtering can be minimized and ripple nearly eliminated. An inexpensive Intersil ICM7555 timer was chosen. This timer, an improved 555 timer, reduces V to ground cross conduction current CC spikes, thereby minimizing bias current requirements ...

Inductances which are in series with each power MOSFET also control di/dt. Stray inductance between the filter capacitor and the positive and negative bus rails help reduce the switching di/dt. In the eval-board, no inductance is added to control the ...

Ultra-fast recovery, 3A rectifiers (UF5405), rectify the 60kHz square-wave voltage waveform. Ultra-fast recovery rectifiers reduce the recovery energy dissipated. Even ultrafast diodes, such as the UF5405, forced a slight reduction in the predicted output power rating of the inverter ...
