48V inverter pre-stage

Can a 48V inverter be rated at 2 kVA?

In this post I have explained a simple 48V inverter circuit which may be rated at as high as 2 KVA. The entire design is configured around a single IC 4047 and a few power transistors. I am a big fan of u....i am a wisp. i need an inverter design with 48volt DC input and 230volt output supply and output power in the range up to 500w.

What is a 48V 12Kw inverter of BSG?

A 48V 12kW inverter of BSG was designed with paralleled TO-Leadless MOSFETs. The phase current was up to 500Arms while the VDS voltage spike was under 70V. The maximum temperature rise of MOSFET was 30°C, and the current of MOSFET was balanced well. This design fulfilled the power requirement with 105°C liquid cooling system.

What is inverter specification?

The inverter specification describes the working condition of the power stage as shown in Table 2. This specification is not directly limited by the power stage. The power stage is designed for such inverter and motor system. The target motor is Permanent Magnet Synchronous Motor (PMSM).

Can I use a Zener based regulator for 48V inverter circuit?

In the above explained 48V inverter circuit I have used a BC546 emitter-follower series pass circuit to step down the 48V DC to 9V DC for supplying the IC 4047. However, if the BC546 transistor is not available, we can incorporate a zener/resistor based regulator for achieving the same results, as shown in the following diagram:

What is IC 4047 in a 48V inverter?

Thanks & Regards Referring to the shown 48V inverter circuit, the IC 4047 forms the main oscillator stage responsible of producing a totem pole outputs for the connected output stage. The output stage is made by configuring a 4 individual high gain high power transistors modules, two of them on each channel of the push pull output stage.

What size power stage should be mounted at the end of a motor?

The power stage should be mounted at the end of the motor, so that there is mechanical boundary of the design. The diameter of the motor is 170mm. There should be place for current sensor and power terminal connecting. The diameter of power stage is defined as 145mm and the height is less than 40mm.
