Pulse’s Gate drive transformers solutions are used as part of the inverter circuit to convert the DC voltage coming from the solar panel or wind turbine (after DC rectification) into a 50/60Hz AC voltage and current waveform, to feed the load and the grid. A range of isolation transformers are available to select from, depending on:
- End-application safety requirements
- Minimum isolation voltage to comply with the applications working voltage.
- Level of insulation (functional, basic, reinforced)
- Minimum safety distances (creepage and clearances)
- End-application electrical requirements
- Selected topology
- Input and output voltages which will dictate the turns ratio
- Operating frequency which, along with the input voltage will set the volt-usecs
- Output power to ensure the selected component is sized correctly
