This H-Bridge Driver Power Module provides for power switching and reverse
polarity outputs with a single power source (and a 5 volt control power). With a
withstand rating of 600 Vdc, it is designed to switch power sources up to about 300 Volts
dc and loads up to 50 amps continuous with natural convection or 80 amps continuous with
100 CFM of air flow and ambient air temperatures to +65C. It can handle switching
125 amps at a 50% duty cycle with 100 CFM of air flow, or 15% duty cycle with natural
Switching transition rise and fall times are relatively fast (< 10
Although for most applications, it would be best practice to switch off
the output prior to switching polarity, the polarity can actually be switched while the
output is ON. The control module ensures the output is OFF prior to switching ON the
opposite polarity, thereby preventing a shoot through short circuit. The OFF duration
delay during a polarity reversal operation is typically about 200 microseconds.
